--delete bug?

[Wayne Davison]

I checked in a fix for this bug (the skipping of --delete when sending
"/" with -R enabled).  I also fixed a couple other things at the same
time:

 - Fixed the bug I found in the --exclude code with -R that allowed "."
   to be affected by an exclude (which would prevent all files in a
   directory from being transferred).

 - Fixed the "mystery" bug in the transfer of "./." (or similar) that
   was causing deletions to be skipped.
