Quick&Dirty "solution": use font-lock information, i.e. look at the face
of the current symbol.

Better solution: Since you are using semantic anyway, you could override
`semantic-ctxt-current-symbol' for C/C++, so that no symbol is returned
when the point is in a comment or string. Eric can surely say if this
would be reasonable to do.

I'm not sure all of this will be fast enough for calling it in something
like 'post-command-hook, though. Maybe this should just be an extra
command, which inserts the correct header for the current symbol, if
necessary?
