Re: Back quote typo in error messages (?)

So I think what you are seeing is not wrong in the sense of being
unintended by the author of the message. But I do think that git mostly
uses matched double or single quotes in its error messages, and the
non-symmetric quotes are relatively rare. Running:

  git grep "\`.*'" -- '*.c' ':!compat'

shows that there are only a few `quoted' cases in the code base (there
are 27 matches, but many of those are false positives, and some are in
comments).

I did a simpler 

    $ git grep "\`%s'"

and saw "`git %s' is aliased to `%s'" from builtin/help.c and
"unknown option `%s'" from parse-options.c (and revision.c)

What Fabrizio saw is the one in parse-options.c, so even though the
number of strings in the code is small, they appear everywhere.

I agree that we should standardise them, and we should do so early
in a cycle, because these appear also in .po files.  It is too late
for this cycle, obviously.
