New Tramp version fails with ssh.

[Luc Teirlinck]

I do C-x C-f on a file using the "/ssh:..." type syntax.
Local machine GNU/Linux, remote machine Solaris2.8.
Result (from *Messages*):

tramp: Finding a suitable `ls' command
tramp: Checking remote `/bin/ls' command for `-n' option
tramp: Testing remote command `/bin/ls' for -n...okay
tramp-check-ls-commands: Invalid function: (macro . #[(variable value
&rest body) "

Then follows some byte code which apparently calls describe-function,
because that is what happens if I try to yank.  Then:

[variable body value if get (quote byte-obsolete-variable) quote progn
let] 6 ("/usr/local/share/emacs/21.3.50/lisp/net/tramp.elc"
. 226654)])

I have a Tramp debug buffer, but it does not seem to contain any more
information.  It ends with:

# Finding a suitable `ls' command
# Checking remote `/bin/ls' command for `-n' option
$ test -x /bin/ls 2>/dev/null; echo tramp_exit_status $? 
tramp_exit_status 0
# Testing remote command `/bin/ls' for -n...
$ /bin/ls -lnd / >/dev/null 2>/dev/null; echo tramp_exit_status $? 
tramp_exit_status 0
# Testing remote command `/bin/ls' for -n...okay
