commit 8147d3c27c breaks grep over tramp

[John Shahid]

Hi all,

Looks like commit 8147d3c27c breaks `grep' when ran on a remote host
using tramp.  Previous to the commit I would see the list of grep hits,
but after this commit there is a command prompt as part of the grep
hits.  This makes the first hit unclickable.  I bisected the history to
find the offending commit and found the following change to be the
cause:

Is anyone else seeing the same thing or is it something with my
configuration ?

Cheers,

Will check. My respective commit message was

    (tramp-sh-handle-make-process): Simplify.

Maybe this part of the patch could simply be withdrawn. I'm short in
time these days, so I cannot promise it will happen before the weekend,
but who knows ...

I do :-(

Obviously, tramp-tests.el must be extended, because they've passed
before I've committed the above patch.

Best regards, Michael.

Thanks for getting back to me.  Take your time, I will revert this
change locally or use a previous commit for now.

I will take a look to see if I can add the missing test coverage.

Should be fixed now in master. I've reverted the change in
tramp-sh-handle-make-process, and I've added a comment to stop me (and
other people) doing the same error, again.

Best regards, Michael.
