Re: Z shell introductory guide source

Sorry for the delay. I slightly modified Doc/Makefie.in
(intro.ms is the same as in the previous post: workers/53137).

'make html' will build both zsh.html and intro.html.

If intro.ms is newer than intro.{pdf,html} and if pdfroff/groff
is not available, 'make intro.{pdf,html}' will fail without
touching intro.{pdf,html} (if they ever exist).
