It's supposed to look like this:

	#!/bin/sh
	/usr/bin/less -EFX "$@"

The install script attempts to create a "more" program (Cygwin doesn't
have one), but the "$1" is being replaced by the argument to the
install script instead of being inserted literally.

The install script on the Baylor site[1] has:

# Need to link more to less for CYGWIN
if [ "$CYGWIN" ] ; then
   if [ ! -x /usr/bin/more ] ; then
      echo "#!/bin/sh" > /usr/bin/more
      echo "/usr/bin/less -EFX $@" >> /usr/bin/more
      chmod a+x /usr/bin/more
   fi
fi

The line:

      echo "/usr/bin/less -EFX $@" >> /usr/bin/more

should be:

      echo '/usr/bin/less -EFX $@' >> /usr/bin/more

Shell variables are substituted within double quotes, but not within
single quotes.

Also the Baylor site is out of date; the latest version is 5.0.0pre3,
but Baylor only has pre2 (and a broken install script).

Can whoever is responsible for the Baylor site at least fix the
install script.
