Subject: Git-related fixes for themes.
X-Git-Url: https://source.supwisdom.com/gerrit/gitweb?a=commitdiff_plain;h=c06ecc53cb87b7017e7869ffbb034b2076b6eed7;p=common%2Fbash_it.git

Git-related fixes for themes.

Improved prompt display speed when git is not installed by
preventing bash from walking the path before each prompt.

Removed pesky stash-related git error message when in bare repos.
