Globbing for directory names with two '='-s fail after 4.2.2.

[Kobayashi Noritada <nori1@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

Globbing for directory names with two '='-s sometimes fails
(i.e. wildcards '*' and '?' don't work) with Zsh after 4.2.2.
It seems to be related to changes in Src/{glob.c,pattern.c} on 2004-10-18.
Since it is a little bit inconvenient for me, I'd like to create a patch
but cannot do so at present.

Is this a known issue?

Detailed reports are in the lower part of this mail.
If I need to offer more information or to do more tests, I'll do so.

Thanks,

  noritada[13:15]%  zsh --version                                   golbeza:~/tmp
  zsh 4.2.4 (i686-pc-linux-gnu)
  noritada[13:16]%  ls *                                            golbeza:~/tmp
  a=b.c_d=e.f:
  hoge
  
  a=b_c=d:
  hoge
  
  bar:
  hoge
  
  foo:
  hoge  hoge2
  
  foo+bar:
  hoge
  
  foo=bar:
  hoge
  
  foo_bar:
  hoge
  
  ra=1.0e7_et=3.5:
  hogebar
  noritada[13:20]%  ls foo/* bar/* foo+bar/* foo=bar/* foo_bar/* a=b.c_d=e.f/* a=b_c=d/*
  a=b.c_d=e.f/hoge  bar/hoge      foo/hoge   foo=bar/hoge
  a=b_c=d/hoge      foo+bar/hoge  foo/hoge2  foo_bar/hoge
  noritada[13:20]%  ls foo/* bar/* foo+bar/* foo=bar/* foo_bar/* a=b.c_d=e.f/* a=b_c=d/* ra=1.0e7_et=3.5/*
  zsh: no matches found: ra=1.0e7_et=3.5/*
  noritada[13:20]%  ls foo/* bar/* foo+bar/* foo=bar/* foo_bar/* a=b.c_d=e.f/* a=b_c=d/* ra=1.0e7_et=3.5/???????

== Occurrence condition

=== Directory name patterns

I tested with various directory names, but couldn't find a rule:

* Success in globbing
  * "ra=1_et=3"
  * "r=.r=."
  * "ra=1.0"
  * "r=1.r=1"
  * "r=1r=1."
  * "r=..=r"
  * ".=."
* Failure in globbing
  * "ra=1.0_et=3.5"
  * "ra=1.0et=3.5"
  * "r=1.r=1."
  * "r=1..r=1"
  * ".=r=."
  * ".==."
  * ".=.="
