Bug involving named pipes and globbing...

[Clueboy]

zsh seems to try to read named pipes as directories when globbing into
directories.  Here's an example:

% echo $ZSH_VERSION                                          ~/test 2:03pm envy
2.6-beta8
% uname -a                                                   ~/test 2:04pm envy

% mkdir test                                                      ~ 1:59pm envy
% cd test                                                         ~ 1:59pm envy
% mkdir dir1 dir2                                            ~/test 2:06pm envy
% touch dir1/a dir1/b dir2/a dir2/b                          ~/test 2:07pm envy
% echo */*                                                   ~/test 2:07pm envy
dir1/a dir1/b dir2/a dir2/b
% mkfifo pipe                                                ~/test 2:07pm envy
% ls -l                                                      ~/test 2:07pm envy
