Can we give him feedback now, asking him to put it back?

I've stopped even TRYING to patch bash. try a for loop calling "echo $$&",
eery single process bash forks off has the PARENT'S value for $$, which is
REALLY annoying if you spend an afternoon writing code not knowing that and
then wonder why the various process's temp file sare stomping each other...

Oh, and anybody who can explain this is welcome to try:

lines=`ls -l | awk '{print "\""$0"\""}'`
for i in $lines
do
echo line:$i
done

Explain please?

The patches-linus-actuall-applies mailing list idea is based on how Linus
says he works: he appends patches he likes to a file and then calls patch -p1
< thatfile after a mail reading session. It wouldn't be too much work for
somebody to write a toy he could use that lets him work about the same way
but forwards the messages to another folder where they can go out on an
otherwise read-only list. (No extra work for Linus. This is EXTREMELY
important, 'cause otherwise he'll never touch it.)

The advantage of this way is:

1) We know who sent the patches. (We get the message with the "from" headers
intact.)

2) Patch mails have descriptions in them most of the time, at least saying
why, if not what they do.

3) This way, we know (more or less in realtime) that Linus has gotten a patch
and applied it to his tree. (What version and everything.) It may be backed
out again later, but we could give him another tool that can do that and
notify the list...

This way, no mucking about with version control, no extra work for Linus, and
in fact he doesn't have to worry about keeping track of what patches he's
applied and when because he has a place he can go check if he forgets.

Now everybody tell me why this won't work. (Sure, all at once, why not...)
