Subject: git-gui: return early when patch fails to apply
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/2ccdfb1c78e1695c4df714887b73ab417ca60f22?ds=inline;hp=--cc

git-gui: return early when patch fails to apply

In the procedure apply_or_revert_range_or_line, if the patch does not
apply successfully, a dialog is shown, but execution proceeds after
that. Instead, return early on error so the parts that come after this
don't work on top of an error state.
