This is not easy to fix.  For C-c C-c we write the text of the
function to a temporary file, compile and load it and remove the file
afterwards.  This means Lispworks records the wrong source location
for the function.  See swank:compile-string-for-emacs.

CMUCL has an extension ext:compile-from-stream which allows us to
attach our custom source info.  M-. in CMUCL works nicely in
combination with C-c C-c.

I'm sure Lispworks has something similar, but I couldn't find it in
the documentation.  Patches welcome :-)
