Hmm.  I did do a search on zsh-workers before I e-mailed the list
about this, but the engine came up with no matches, and for some
reason, I still can't get any query similar to
`zsh.texi;given;once;rule' to produce the relevant articles, even with
`partial match' switched on.  Anyway, thanks for the pointers, and
sorry for the extra noise.  Just for reference, I think you meant 9587
rather than 9687.

Maybe that's because you followed your suggestion with `That's what
bash does.' ;-)

Anyway, this needs to be resolved fairly swiftly, as presumably anyone
using gmake is currently unable to build the docs.  I don't know
enough about the Makefile structure in general to comment on your
suggestion, but here's another suggestion which feel free to shoot
down in flames :-)  It works for when sdir is `.', but is untested
otherwise.
