I've noticed a problem that's likely related.

When I do M-x grep and use

  grep -nH -e "(define-minor-mode" lisp/*.el

I get a *grep* buffer with occurrences of "(define-minor-mode" in lisp
files.  Every time that I tried, most lines in this buffer give the
text "(define-minor-mode" the grep-match-face, but a few lines don't
fontify "(define-minor-mode".  The strange thing is that the lines
that don't fontify "(define-minor-mode" are different every time I
invoke grep.

I've got a sneaky suspicion that something goes awry with the
interaction between font-locking and the code in
grep-mode-font-lock-keywords that removes the escape sequences.

Lute.

Very wild guess.  Please do C-h v tramp-chunksize RET and run the Lisp
code shown in the documentation for tramp-chunksize and report your
findings.

The Lisp snippet contains a number, 1000.  If you do not observe a
problem (i.e., you that bytes sent always equals bytes received), then
please also try larger values, 10000 or 100000 or 1000000.
