[PATCH 2/3] bash prompt: remove a redundant command line option

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To get the dirty state indicator __git_ps1() runs 'git diff' with
'--quiet --exit-code' options.  '--quiet' already implies
'--exit-code', so the latter is unnecessary and can be removed.
