6-pws-2

[Peter Stephenson <pws@xxxxxxxxxxxxxxxxx>]

I have probably uploaded
http://www.ifh.de/~pws/computing/zsh-3.1.6-pws-2.tar.gz

- This covers patches to 7551 with exceptions noted

- As I just mentioned, email to here isn't working, use pws@xxxxxx if rnsr is
  requid.

- There's an exec.c patch from Tanaka Akira, 7436, left out, because it was
  followed by an inconclusive discussion.  It's supposed to fix exec'ing
  the last element of the last pipeline.  I have not looked at the problem.

- Updates to the completion system may be bungled.  I received some of the
  patches in random order and could have skipped others because there were
  many similar.

- I only deleted Completion/User/_cvs after making 6-pws-2, delete it
  by hand for now.  Let me know of other completion functions which are
  now redundant.

- Personally, I prefer one single completion function for a suite of
  related commands like cvs or pbm, since the accumulated clutter (and
  added time to process completion files the first time) is large.  If it
  stays the way it is I will change the default for function installation
  to keep the subdirectories.

- I haven't looked at the speed of the new pattern matching code.  If case
  statements with *only* simple strings are slower, there's not much I can
  do since it's already optimised to a strcmp(), though I think I can speed
  up the string-building loop in patcompatom().  In other cases I can think
  of a few tweaks.

- If there are any firm suggestions on how pattern matching in ${...},
  particularly substrings, should be changed, please post a summary.

- I still feel the new glob qualifiers for calling code to decide on files
  to include may be overcomplicated.

- Telling me it's time to put together a new development version while I'm
  away may not be a very productive exercise.

- I've moved some files around and corrected a small typo (_arguements) in
  _tar.

- There are lots of things I've probably forgotten; it's taken me most of
  the day just to catch up with the patches.  If you submitted a suggestion
  (rather than a patch) for something like a configuration change then it's
  probably gone in one ear and out the other.
