Paul,

base-files is a source-only package.  Also, this is the appropriate place
for patches.  I'm sure the base-files maintainer reads this list.

FWIW, this problem has been reported before.  One of the solutions
previously proposed for this problem was adding the various
capitalizations of "bash" to the case, i.e.,

case "$0" in
[Bb][Aa][Ss][Hh]              | -[Bb][Aa][Ss][Hh]              | */[Bb][Aa][Ss][Hh] | \
[Bb][Aa][Ss][Hh].[Ee][Xx][Ee] | -[Bb][Aa][Ss][Hh].[Ee][Xx][Ee] | */[Bb][Aa][Ss][Hh].[Ee][Xx][Ee] )
 # Set a HOSTNAME variable

Your solution looks cleaner, although, as Karl pointed out, it can be
shortened to the following (also made space-in-filename friendly):

case "`echo "$0" | tr [:upper:] [:lower:]`" in
bash     | -bash     | */bash | \
bash.exe | -bash.exe | */bash.exe )
 # Set a HOSTNAME variable

There is also a typo in the ksh section of the default profile (HOSTNAME
is not set), for which, IIRC, a patch has been submitted a while ago, and
the PRINTER setting for WinME is missing (also with a pending patch).
John, are you reading this?
