This may be easier than I thought, look:

It may be a simple matter of modifying the DEFUN macros to include
__FILE__ and __LINE__ information, with perhaps some path prefix
information, and then using this information from the edit or help
commands. (The __FUNCTION__ macro isn't standard CPP, but it seems of
limited use for this case anyways.)

I hope it really is easy...
