[PATCH v2 0/4] --word-regex sanity checking and such

I wrote:

* [4/4] I stole the html test from Scott's mail, and some of the rest
  from various Wikibooks sources on "Hello World" in each language,
  usually extended by a bit of code that tests the world-splitting
  power.  I hope this is ok with Scott and the Copyright overlords.
  There are only so many ways to spell "Hello World", and only so many
  languages I know myself.

I decided to play it safe, and removed these parts.  In addition I
extended the bulk tests to a C operator table and some forms of
literals for the C-style languages so as to catch issues with
non-matches.  This showed that the python regex had the same typo as
the ruby one. *blush*

Scott's problem still remains:

Fedora Core release 6 (Zod)

I briefly considered installing FC6 on a VM, but my VirtualBox is
broken and I'm having a hard time finding a FC6 installation medium.
Right now the only other systems I have are darwin 10.5 and RHEL5.5,
and the test works on both.

So in the absence of any way of testing this, someone with a breaking
system will have to investigate.  I think it's worth including the
series anyway, since the regexes give wrong results in the case of
match failures, and we would want users to know about this.
