Thanks I changed it to '[ $# -eq 0 ]', which is more portable yet, as it works 
even if a purposely-pedantic shell sets $# to '00'.

Hi!

In emacs git as of yesterday, test/indent/shell.sh contains the
unportable '==' comparison operator for test(1) -- only bash supports
that, not even GNU coreutils' test(1).

Please use '=' instead; see attached patch.

Thanks,
 Thomas

P.S.: I know it's not intended to be executed, but I'd like to avoid
having bad examples around :)
