Subject: rebase -i: notice and warn if "exec $cmd" modifies the index or the working tree
X-Git-Tag: v1.7.7.1~23^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1686519a0854ec09ee1cdd6db7f570ea4590dfce;p=git.git

rebase -i: notice and warn if "exec $cmd" modifies the index or the working tree

If "exec $cmd" touched the index or the working tree, and exited with
non-zero status, the code did not check and warn that there now are
uncommitted changes.
