Hi Michael!

Your fix fixed one of the issues. (file-regular-p) now works as expected 
over TRAMP ftp.

I can't reproduce the other one right now. There must be some kind of 
cache influencing the other issue.. I deleted the tramp directory but it 
had no effect.. I'll make a new report if I find a way to reproduce the 
other issue.

Regards
Christian
