Thank you, but I think you misunderstood. The problem at hand (in this
bug report) _is_ the problem with how `find-library-name' handles paths;
I don't see any problem with the suffixes as in your bug report.
As I wrote in the mail you quote above, `find-library-name' passes an
absolute pathname to `locate-file', which makes no sense. That's the
basic symptom of what needs to be cured (although as Stefan points out,
simply removing the path component is probably not the right solution);
it has nothing to do with {find-library,get-load,load-file-rep}-suffixes
or file name completion.

Wouldn't it be better to discuss this on emacs-devel or file another bug
report? I really don't see any relation here.
