I see ... so how can we stop make from complaining when sdir is `.' ?
If we're compiling in a separate build tree then presumably we don't
need a rule for the source tree version of zsh.texi, so can we just
get rid of the zsh.texi target and leave the $(dir)/zsh.texi one?  If
we can, the patch is below.  However noone else seems to have
encountered a problem with this (and neither did I before Christmas),
so it's more likely I've done something wrong.  Any ideas what?
