In situations where `ls` colors directories incorrectly, the `$module`
variable contains unprintable characters. This causes directories to be
impossible to `cd` into normally, and is generally a pain.

bash might not be in /bin. Don't expect it there.

Use a consistent standard - Tabs in front for indenting, spaces after for anything else. This way everything stays nice and lined up while also letting users change there prefered indent level. Most of the new files from Haata where already in this format.
