Doug Davis 116367eb07 Fix for help when $HOME is /
estesp noticed that when $HOME is / the ~ substitutions messes up
becuase it tries to replace all paths that start with "/" with "~".
This fixes it so that it will only replace it when $HOME isn't "/".

Package mflag (aka multiple-flag) implements command-line flag parsing.
It's an hacky fork of the official golang package

It adds:

  • both short and long flag version
    ./example -s red ./example --string blue

  • multiple names for the same option

$>./example -h
Usage of example:
  -s, --string="": a simple string

It is very flexible on purpose, so you can do things like:

$>./example -h
Usage of example:
  -s, -string, --string="": a simple string

Or:

$>./example -h
Usage of example:
  -oldflag, --newflag="": a simple string

You can also hide some flags from the usage, so if we want only --newflag:

$>./example -h
Usage of example:
  --newflag="": a simple string
$>./example -oldflag str
str

See example.go for more details.
