I moved the configuration to cygwin_setup_config.bat.

Meh.  .bat is what I have always used.

I was surprised as well when I saw that it worked. Normally I do put the
redirects after the command.  This was a copy-n-paste job.  I moved them
to the end to be consistent.

Actually, EQU is correct.  From "if /?":
  where compare-op may be one of:
    EQU - equal

I changed to the "if [not] errorlevel <number>" syntax to reduce the
dependancies on extended mode.  Note that there are probably other
places that depend upon extended mode.

You are correct.  I normally quote filenames when expanding them, I just
missed that one.  Fixed.

I added the call to rebaseall because of this post by Corinna:

  http://cygwin.com/ml/cygwin/2012-08/msg00320.html

Installing more packages that are forgotten in the first run of
setup.exe is what I (and I suspect others) do all the time.  I would
love to get some feedback either way on this issue.

There are some native speakers who I wish were as literate as you.
