Re: [PATCH] Show presense of stashed changes in bash prompt.

[Daniel Trstenjak <daniel.trstenjak@online.de>]

Avoid the forgetting of stashed changes by showing
them in the bash prompt.

If the presense is shown is configurable by setting
GIT_PS1_SHOWSTASHSTATE to a nonempty value.

The code for checking if the stash has entries is
taken from 'git-stash.sh'.
