split my long stderr message, displaying details only if called by raw_input

Rather than overwhelming users with verbiage, I will hide most of my explanation unless it's asked for. My message is still not particularly brief, but it's no longer insanely long.

Explanation:
Windows' use of the backslash as a directory separator is clashing with the use of the backslash as an escape. As an escape, the backslash tells your system that you want a normally special character to be its literal self (or sometimes, that you want a normally ordinary character to have a special meaning). Your system interprets '\\"' as an escape for a literal quote character. Two quotes together are also interpreted as a literal quote.
'"Campaign\\"' is interpreted as 'Campaign"' instead of 'Campaign\\'.
'"My Folder\\"Campaign' is interpreted as 'My Folder"Campaign' (not 'My Folder\Campaign').
'"My Folder\Campaign\\" "My Folder\Another_Campaign"' is interpreted as 'My Folder\Campaign" My' and 'Folder\Another_Campaign'.
In your case, your system interprets your arguments as:
