tcsh and chere-0.3-1

[Andrew Grimm <agrimm at redwood dot rsc dot raytheon dot com>]

The new (very cool!) chere package doesn't work with tcsh, at least on my
system.  The problem is that "tcsh -l" doesn't work with any additional
arguments.  There is even a comment to that effect in the script:

tcsh )
        # Apparently -l only applies if it is the only argument
        # so this may not work
        SHELL_EXE="/bin/tcsh.exe"
        SHELL_CMD="-l -c \\\"cd '%L'; exec $SHELL_EXE\\\""

If I run this, the tcsh immediately bombs out, closing the shell window,
because tcsh exits when it sees the additional arguments.

There may not be a perfect solution because tcsh won't work with the
code pattern used for the other shells.  If you make the exec'd shell a
login shell it cd's to your home directory which defeats the purpose of
the package.  This hack works for me, it doesn't create a real login
shell but it fakes one fairly well:

        SHELL_CMD="-f -c \\\"if ( -f /etc/csh.login ) source
/etc/csh.login; if ( -f /etc/csh.cshrc ) source /etc/csh.cshrc; if ( -f
~/.tcshrc ) source ~/.tcshrc; if ( -f ~/.login ) source ~/.login; cd '%L';
exec $SHELL_EXE\\\""

A more complicated line could be created to handle more unusual tcsh
configurations but this approach works with the default setup.

      modification to line 244 of the chere script):
