For all of you C-shell fans - heres a couple of bugs/puzzles.  (I don't know
the answer to the second.)

The following alias should give a directory listing of the files which have a
specified pattern in the middle.  It only works if the pattern is at the end.

	alias lm 'ls -l *\!**'

Its easy to make it work, but I think that the above is acceptable.

The next has to do with how do you run a command which has nested command
substitutions?  From what I can see, you cannot.  I would love to be able
to type (in a more complicated shell script and using any amount of quoting
necessary)

	echo `echo `date``

but no amount of quoting seems to satisfy the shell.  Any ideas?  (I know -
RTFM, but I have grepped sh and csh for nest, recurs, ... and have come up
empty.)  Any suggestions would be appreciated.  Both problems exist on
Suns and Ultrix 1.0.
