FYI: AS_BASENAME no longer shell-quotes its argument

[Paul Eggert]

After I regenerated "configure" with the new autoconf, I found one
minor problem -- m4sh.m4 assumed that AS_BASENAME shell-quotes
its argument, but the new AS_BASENAME does not do that (for compatibility
with AS_DIRNAME).  I installed this patch and then installed the
regenerated "configure".

        * lib/m4sugar/m4sh.m4 (as_me): Shell-quote the argument of
        AS_BASENAME, in case $0 contains white space.
