Actually that was not what I meant.  I thought we might need to
support something like:

	core.htmlprogram = grand-unified-help %b

for a program that knows where in the system the distribution
keeps help HTML files, and add prefix (/usr/share/html-help/,
perhaps) and suffix (obviously, .html) to the basename of the
command (e.g. "grand-unified-help git-rebase" ends up running
"lynx file:///usr/share/html-help/git-rebase.html"), or perhaps

	core.htmlprogram = firefox /usr/share/html-help/%f

and we substitute '%f' with "git-rebase.html".

File existence?  I am not sure what you mean by that, sorry.
