Splitting out this function bothered me. It is conceptially similar to
file_pruned, and yet also very specific to exactly the security needs of
find_src_files.
I liked that it got rid of duplicate code in the latter function. So
instead, put a helper sub in that, which I think allows refactoring
things more cleanly, and with less boilerplate.
As to the needs of gen_autofile, I'm not convinced this needs to handle
the same set of problems that verify_src_file did. So I sat down and
wrote a custom validator for autofiles, which turned out to seem to just
need three things: Make sure the candidate filename is not something
that would be pruned; untaint the candidate filename; and make sure that
srcdir doesn't already have something with its name. (Plus, of course,
all the other checks that were already in gen_autofile.)
(In passing, also fixed a bunch of bugs I had introduced in this branch.)
With this change, the <span> with class createlink is always created
around the link text, even when no CGI URL is defined. This allows
styling of these 'links' in this case too. The same class is used as when
CGI URL is defined so that e.g. clones of the same ikiwiki, one with CGI
and one without, display in the same way (modulo the missing question mark
link).

By a stroke of luck, after a long & full day, I happened to
remember that in the morning, I had seen someone on irc mention
that darcs query manifest doesn't like it if its full output
is not consumed.
So contrary to the usual case where bug reports sent via irc are like
messages written in sand before the new tide, this one was seen and
fixed.
(But use http://ikiwiki.info/bugs/ next time!)
$cgi->params('do') may not be defined. The CSRF code may delete all
cgi params. This uninitalized value was introduced when do=register
support was added recently.
Many calls to file_prune were incorrectly calling it with 2 parameters.
In cases where the filename being checked is relative to the srcdir,
that is not needed.
Made absolute filenames be pruned. (This won't work for the 2 parameter call
style.)
