Unit text fixes for meta-bug #10960.

I'm still unhappy with this text; it needs a careful rewrite when I'm
not under time pressure.  But it least we can ship this without
looking like illiterate dimwits.

-Almost every orc are a member of a tribe or a clan. Relations between neighbouring tribes are usually violent, except in cases of a mutual enemy threatens their existence or prospects of great plunder overrides mutual animosity. In addition, a single strong chieftain may emerge to lead multiple tribes from time to time, usually through intimidation of followers. An orc tribe in times of peace tends to almost solely focus on strengthening itself in preparation for the next armed conflict. Orcs are known to possess a very simple system for symbolic writing - usually in blood - although it's most commonly used to trade insults or threats between tribal leaders.

-Orc societies are based on little else but strength; might makes right, and a leader leads and survives only as long as no one manages to wrest the title from him. A constant struggle usually exists for power between potential tribal chiefs. An orcish leader rarely lives more than a handful of years to enjoy his absolute authority before being killed for his position - although history knows some notable exceptions. Orcs hold no particular honour code and while undisputable raw strength is usually the preferred method of displaying power, assassination, poisoning and backstabbing are completely viable means to further one's own goals.

 Orcs mostly live in rural areas, often in foothills or mountainous regions, sometimes in caves. They grow no crops nor keep livestock, but are competent hunters as a result of their physical stature and brutality. Due to their large numbers they are capable of hunting an area virtually clean of anything larger than rodents in relatively short period of time. Due to this and their unstable leadership, orcish tribes tend to lead a semi-nomadic lifestyle, never settling in one region for too long. The larger tribes may establish themselves firmly in an area for years or even decades and build large encampments almost resembling cities, but even these are easily dismantled and abandoned if there is a need to relocate the horde.
 
-The oldest known orcs have been around 50 to 60 years of age, but very few individuals ever live to see over two or three decades before meeting their end either in war or by the hand of one of their kin. The oldest orcs are often shamans, which are perhaps the only ones most of their kind sees as being trustworthy and neutral. The origins for this custom are unknown, as the shamans do not directly contribute much to orcish societies but only act as advisors, which is not something orcs tend to otherwise tolerate. Shamans are in many ways the opposite of almost every other orc: they are often physically withered and frail in comparison and lack skill in battle. Despite their reliance on raw strength, not nearly all orcs are destined to grow to possess any. Many orcs are born smaller and weaker than the rest, and already almost as newborns are put in their place by their stronger siblings. The stronger ones will routinely grab most of the food and thus grow stronger still, while their weaker siblings do not. Many of these individuals tend to specialize in other skills, like archery or assassination."

         description= _"Trolls are ancient creatures, one of the oldest known races known to inhabit the Great Continent. They are large, slow, simple-minded, and live extremely long lives inside deep caves or atop high mountains. The most unique characteristic of trolls is an internal vitality that sustains and heals them from within. As a result they live very different lives from almost any known creature. Trolls have few real needs: they require little food or water, and thus they have little incentive to pursue much besides protection from those who are hostile towards them. This in turn means they rarely have to worry about anything and can spend much of their time sleeping or in contemplation. Trolls have a curious affinity with nature. They do not relate with living things like elves do, but instead with earth and stone. They are also somewhat curious of their surroundings and many younger whelps even enjoy traveling and seeing the world. As trolls grow older they tend to become increasingly passive, gradually losing interest in their environment and spending more of their time sleeping in a quiet, familiar corner of their home cave. This is until they finally pass away as their bodies themselves slowly turn into lifeless statues of stone.
 
-Trolls are seen by many as being little more than a yet another race of savage monsters. This common misconception is in part perpetuated by orc to persuade trolls to join their armies. Because they are rather simple and do not understand the ways of other races or sometimes can even tell them apart, it is usually easy for an orcish band to convince a group of trolls that by joining them they get to exact revenge on those that have before hunted them. These new recruits are then directed to attack whoever the orcs themselves are currently in conflict with, whether previously a foe of the trolls or not, accumulating even more enemies for the misled trolls. The most common enemy of trolls are dwarves, and the animosity between these two races is ancient.

 Trolls have inhabited the mountains of the Great Continent longer than the dwarves who migrated there. Trolls are a common sight on the mountain ranges north and east of Wesnoth, and wherever Orcish hordes travel."
