nohup "broken" after update of cygwin from 1.5.9->1.5.12 -- keychain and ssh-agent broken at least...

[Peter Valdemar Mørch <swp5jhu02 at sneakemail dot com>]

Hi there,

My problem seems to boil down to this: If I have this simple batch file 
and dbl. click on it:
\cygwin\bin\bash -c "/usr/bin/nohup /usr/bin/ssh-agent -s"

With 1.5.9, this batch file would finish, the MS-DOS box would 
disappear, and ssh-agent would be operative and in the task list. With 
1.5.12, the MS-DOS box lingers on, and if I close the MS-DOS box, 
ssh-agent is killed.

Any idea why?

Here is the output from uname -a (new/old):
CYGWIN_NT-5.1 pvmXP 1.5.12(0.116/4/2) 2004-11-10 08:34 i686 unknown 
unknown Cygwin
CYGWIN_NT-5.1 pvmXP 1.5.9(0.112/4/2) 2004-03-18 23:05 i686 unknown 
unknown Cygwin

I don't mind supplying /etc/setup/installed.db, but don't know what to 
show...

Details:

I have a batch file in my Start\Programs\Startup folder that ran
/usr/bin/keychain with this .bat syntax:
\cygwin\bin\bash -c "keychain `ls ~/.ssh/id*|grep -v '\.pub$'`"

It used to prompt me for my password, then finish (and the MS-DOS box
went away).

However, after updating today to the most recent "of everything", now
the behavior has changed. The MS-DOS box just sits there. If I try to
close it, I get the Windows "End Program" window, and closing it, kills
ssh-agent.

After the upgrade, I now have to start ssh-agent myself very carefully. 
(see code snippet below in batch file diff)

/usr/bin/keychain is identical to what it was.
