folding ifdefs
Since adding support for debugging to my latest c++ code, it's become
ugly with #ifdefs. Wouldn't it be cool to be able to fold them away?
Since C-mode already knows how to parse the ifdefs and find the
matching endif (the hard part), it may be possible to add such a
feature. I imagine being able to set local file variables to make all
that crap disappear, for example.
