[Message part 3 (text/plain, inline)]

Grep over tramp fails to insert header in its output buffer. (I remember
reporting this bug, but I didn't notice it was about tramp then; I tried
with 'emacs -q' now).

For example, run from *scratch*, as 'M-x grep RET grep -nH -e xxx xxx RET':

    -*- mode: grep; default-directory: "~/" -*-
    Grep started at Thu Dec 12 14:33:28

    grep -nH -e xxx xxx
    grep: xxx: No such file or directory

    Grep exited abnormally with code 2 at Thu Dec 12 14:33:28

But when run from a "tramped" buffer ('/sudo:root <at> localhost', but
apparently true for any other case too) in the same way:

    grep: xxx: No such file or directory

    Grep exited abnormally with code 2 at Thu Dec 12 14:35:53

I've fixed this now, changes committed to the repositories. Closing the bug.
