Subject: git-gui: Allow as few as 0 lines of diff context
X-Git-Tag: gitgui-0.7.3~44
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=b8848f7753762ff8c4e34b3c15e788c5f7e6781f;p=git.git

git-gui: Allow as few as 0 lines of diff context

Johannes Sixt pointed out that dropping to 0 lines of context
does allow the user to get more fine-grained hunk selection,
especially since we don't currently support "highlight and
apply (or revert)".
