Versions found by wildcard URLs are different from versions found by
parse_version, etc. The wildcards are constructed more haphazardly
than the very specific URL patterns in url.py, so they can get things
wrong. e.g., for this URL:
https://software.lanl.gov/MeshTools/trac/attachment/wiki/WikiStart/mstk-2.25rc1.tgz
We miss the 'rc' and only return 2.25r as the version if we ONLY use
URL wildcards.
Future: Maybe use the regexes from url.py to scrape web pages, and
then compare them for similarity with the original URL, instead of
trying to make a structured wildcard URL pattern? This might yield
better results.
