Since c9d961647 (i18n: add--interactive: mark
edit_hunk_manually message for translation, 2016-12-14),
when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:
/^$commentChar/
If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).
We can fix that by telling perl not to respect
metacharacters.

I did this on the current master. It also applies cleanly on top of
'maint'. The fix applies back as far as c9d961647, but t3701 grew some
new tests in the interim, so there's a minor conflict applying it there.
