Re: sh compatibility again :->

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxxxxxxxxx>]

} The only way to resolve this would be with yet another option, SH_QUOTES
} or some such.  Worth it?  Dunno.

This is a ridiculously simple patch, so in case anybody wants it ... note
that this makes live the DPUTS(!*str, "Oops ...") error in the walk-off-
end-of-a-string loop for which I sent a patch last week, so you probably
want that earlier patch as well.

The only question about this patch is whether

+    int shq = (endchar == '"' && isset(SHQUOTES));

ought to be

+    int shq = ((endchar == '\0' || endchar == '"') && isset(SHQUOTES));

I actually think perhaps it should.
