Re: Fwd: REVIEW REQUEST - user manual generation

Indeed, I don't believe there is any perfect way to support filenames
with spaces.  Double-quoted "foo bar.tex" is the most likely.
I don't know if that works in miktex.  Multiple consecutive spaces is
even harder, e.g., see thread starting at
http://tug.org/pipermail/tex-live/2016-May/038331.html.

I believe luatex has enhanced the \input primitive so that if the next
character is catcode 1, the filename is terminated by the next catcode 2
token.  I'd like to do this in all the engines (except "tex"), but even
if we did, and got christian to do it in miktex, it would still be a
hassle in texi2dvi to detect whether that support is present.  :(  -k
