Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In an arbitrary directory, for example in /tmp , I have a file named 
iptraffic.log and a directory called iptrafvol. In emacs I type C-x C-f 
to try to load iptraffic.log and type "/tmp/ip<tab>" where <tab> means 
the tab key. Then tab completion completes to the "/tmp/iptrafvol/" 
directory and ignores the iptraffic.log file.

Fundamental principle of Buddhism is purposelessness. Most important
to attain state of no purpose. When you drop fart, you don't say 'At
9:00, I drop fart.' It just happen.
