------------------------------------------------------------------------
----------------------------
I just installed the 23.1 release on Windows XP and I noticed two
problems:

1. M-x grep-find takes 5-7 sec to show the standard command "find .
-type f -print0 | xargs -0 -e grep -n". 
In the previous version 22.3 it appeared immediately.

2. When I type M-x find-file then d:/te <TAB> it proposes two completion
"temp" and "telnet:". 
I dont have "telnet:" file on my disk d:/   In the previos version 22.3
it was completed immediately to
d:/temp/

Only the first time, right?  If so, that's because Emacs tries to
figure out what kind of programs you have for this pipe.  You can
avoid the delay by customizing the option `grep-find-command'.

Does this happen in "emacs -Q"?  I cannot reproduce this on my
machine.  I see that you have many non-default modes enabled:

Maybe one of them causes this problem?

bug#4046: 23.1; minibuffer completion

[Pavliv Oleg]

I found a reason for a grep-find slowness

It is necessary to put in .emacs
(setq grep-highlight-matches nil)
or
(setq grep-highlight-matches t)
to avoid a call (grep-probe) which takes a long time

In the previous version of emacs 22.3 it was nil.

As for telnet: file I don't know yet. Emacs is started with the only
option --debug-init 

Thanks
Oleg Pavliv
