"unescaped character literals detected"

[Eli Zaretskii <eliz@gnu.org>]

Compiling the Lisp files in the current master produces quite a few of
these new warnings, see below.  I hope someone is looking into
eliminating them, otherwise we introduced a safety feature that does
nothing except annoying us.

Also, there seem to be several instances of the same warning, only one
of which points out the line number where the problem happens.  Is it
possible to output only that final warning?  The rest of them, those
without a line number, are useless, as there's no practical way of
finding the offending code unless you know exactly what to look for
(and the wording isn't specific enough to allow the latter).

Thanks.
