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

I use the mini-buffer completion mode quite a lot. For the most part it seems
to work just fine.

However, at time, it seems to completely complete at times when there are
ambiguous entries.

I also have the case-ignore variable set to ignore character case.

Usually it is when I am in RMAIL an outputting a message to a folder. I will
do something like this

o            output to folder
all<tab>     finds ALLMAIL
new<tab>     finds NEWJOB
bo<tab>   

At this point it would pick the folder bob automatically. This ignorged the
fact that there was a "borg" folder. If I delete back to "bo" then hit <tab>
it will show both selections as I originally expected.

Let me know if you need my .emacs file
