Subject: [PATCH] make: ctags: Limited prototype tags to header files

Jumping to prototypes in header files is extremely useful, because
that's usually where all the documentation is. But jumping to prototypes
in C files is a bit much. These are usually just uncomment definitions
to keep the compiler happy, and make navigation a bit of a pain.

Unfortunately it doesn't seem like ctags supports per-file-type tag
kinds (at least I couldn't find it in the documentation), but running
ctags twice with the --append flag seems to work.
