It's another option.
The main point i proposed reading the files separatedly is because I think
that most time spent on parsing files is on duchain building instead of file
parsing itself, so that reading the files again with a regular parser should
be real fast ("wcgrep TODO" in kdevplatform takes 5.5 seconds in my system
on the first run, when it's cached it's blazingly fast, <0.1s). Also using
different regex would make it possible to gather information also from other
languages (python, bash, perl,...) where language support is not as
important as for c++ but we still might want to know about its TODO's.

Also I'm not sure we want to add Problems from the users, since they're not
problems, just issues we have to track down.
