Rats. I had tried some others, too, but missed (inter alia) these two.

It's *much* worse:

  % ls
  <aa  >bb
  % a='\<*' b='\>*'
  % echo $~a
  <aa
  % echo $~b
  zsh: no match
  % setopt shglob
  % echo $~a
  zsh: no match
  % echo $~b
  zsh: no match
  %

All this is caused by tokenize() treating backslashes differently.

I wanted to not commit this patch right now, but to compile the shell
I had to fix a pathmax bug in parameter.c and that has to go in. So,
let's just try it. Most of the patch is for unsetopting shglob in
completion functions and for _expand and _path_files to get quoting
right. At least I've tried several things needing quoting and they
were all handled correctly.


There is another problem with the pathmax stuff: with the files
module, doing `mkdir foo' fails because it tries to get the pathname
length of a non-existing directory. Haven't checked if there are other 
builtins with this problem.
