   Coming from a (SunOS 3.5) csh environment, there are a few things I'd
   really like to see in bash:

   For history, a few inconsistancies:
   There is no :gs operator for replacing on the whole line.
   e.g.
	   % echo hello hello
	   hello hello
	   % !!:gs/ll/xdr/
	   echo hexdro hexdro
	   hexdro hexdro

That is right, I didn't write a `g'lobal operator.  I may add one in the
future.

   And the existing :s operator doesn't do delimiter-escaping or
   &-expanding.
   e.g.
	   % echo qweryuiop
	   qweryuiop
	   % !!:s/qwer/&t
	   echo qwertyuiop
	   qwertyuiop

THe ampersand is replaced by the matched text?  What if you are just
adding an ampersand, which seems to me to be a common case:

	bash$ hairy-function argument
	bash$ !!:s/argument/another-argument &	<- user wants to background this job.

	   % echo hello/world 
	   hello/world
	   % !!:s/llo\/wo/ll0\/wo/
	   echo hell0/world
	   hell0/world

I didn't do delimiter escaping.  However, the first character following
the `:s' is the delimiter, so you can choose it when typing in the
substitution request.  For example:

	!!:s@llo/wo@ll0/wo

would do what you wanted.


   2)  When starting window tools in the background, they inherit the tty
   state from bash and use that for the command window.  (The tool I
   notice this from is Sun's dbxtool).  This leaves the dbxtool command
   window in cbreak/noecho mode.  Most annoying.  And you can't start it
   in foreground and then ^Z it as dbxtool ignores ^z.  Dammit.

I have fixed this (to the best of my knowledge) in 1.03.

   3) Sun csh does completion on ~u<ESC> for usernames.  A useful feature
   I may add one day.

It is in 1.03.

   4) Sun csh, when given a "cd dir1" will try current dir, then cdpath,
   then a shell/environment variable called "dir1".  I've found this
   really usefull for working on multiple versions of the one source: a
   command can set shell variables for make, etc, and vars for src, run,
   lib etc. Then "cd run" changes to the correct run directory.  Again,
   should be easy to add.  The sun version didn't know about paths, so
   perhaps you could make "cd dir1/dir2" equivalent to "cd $dir1/dir2".

New variable in 1.03. "cdable_dirs", if it exists, says to do exactly
that with arguments to pushd and cd.
