Is anybody maintaining c2z and lete2ctl?

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxx>]

I noticed they haven't changed for quite some time (at least, not in the
zsh 3.0.x sources, I haven't checked 3.1.x).

Here are a batch of tweaks to the 3.0.4 c2z:

* Fix the usage comment
 (can't give both -l and -i, must use one or the other)
* Optionally take the name of a file to convert
  (instead of always converting .cshrc and optionally also .login)
* Use $ZSH_NAME in preference to $VERSION to detect zsh
  (hopefully nobody exports ZSH_NAME and then runs `sh')
* Change $cwd to $PWD in aliases converted to functions
* Delete assignment to PWD from the environment
* Fix handling of tcsh `correct' variable
  (what was `setopt autocorrect' supposed to do?)
* Upcase all `prompt' variables
  (zsh maps prompt->PROMPT but not prompt2->PROMPT2 et. al.)
* Change `!' to `%h' in PROMPT
  (old csh history number references)

There are probably other tcsh-isms that could be incorporated.
