Re: [PATCH] branch: issue "-l" deprecation warning after pager starts

By the way, this is one of these times when I feel that we should
have a better multi-line message support in die/error/warning/info
functions.  Ideally, I should be able to write

	warning(_("the '-l' option is an alias for '--create-reflog' and\n"
		  "has no effect in list mode, This option will soon be\n"
		  "removed and you should omit it (or use '--list' instead)."));

and warning() would:

 - do the sprintf formatting thing as necessary to prepare a long multi-line
   message;

 - chomp that into lines at '\n' boundary; and

 - give each of these lines with _("warning: ") prefixed.

That way, translators can choose to make the resulting message to
different number of lines from the original easily.

Yep, I totally agree. In past discussions I was thinking mostly of
the pain of writing these multi-line messages. But I imagine it is
absolute hell for translators, and we should fix it for that reason.

(Also, I guess this message probably ought to be marked for
translation).

Needless to tell you, I worked backwards when noticing that these
three warning() lines are not marked for translation ;-).

But of course, fixing this in a naïve way will involve memory
allocation during execution of die(), which may well be due to OOM,
which is why we knew the need but haven't found a good solution to
it.
