[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_SHOW_STASH_STATE to a nonempty value.

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