Ruby CVS system() bug?

ri says system should return false if the command failed, but if the
file doesn't exist, my version of ruby returns Errno::ENOENT.

I noticed it because Instiki 0.9.1 tries to detect pdflatex like this:

rasputin@lb:instiki-0.9.1$ grep pdflatex instiki.rb |head -1
pdflatex_available = system "pdflatex -version"

which goes boom like so:

rasputin@lb:instiki-0.9.1$ ruby instiki.rb
instiki.rb:21:in `system': No such file or directory - pdflatex -version (Errno::ENOENT)
        from instiki.rb:21
rasputin@lb:instiki-0.9.1$ ruby -v
ruby 1.9.0 (2004-07-01) [i386-netbsdelf2.0F]
rasputin@lb:instiki-0.9.1$

It looks like whoever updated the source forgot to update the RDoc comment.

It looks like whoever updated the source forgot to update the RDoc
comment.

My gut reaction was that this was a bug in system. It makes more sense
to me for the documented behaviour to happen, but maybe that's just
the context I'm looking at it from...

Dick,

Check the archives (or Google Groups) for more information on this --
the change is known, and was discussed at length a couple of weeks
ago.

Thanks, I sent a patch to David.
