Tramp questions

[Gabor Greif]

Hi all,

first of all, big thank you to all who have developed and as
maintaining emacs tramp. It is a truly great tool and have saved me
from countless headaches!

Some remarks and questions follow...

1) Is there a method which instead of sending back entire files, sends
only the diffs to the last saved checkpoint of the file? Something
like '/ssh+patch:...' ? I ask, because in my setup download is very
fast, but upstream is unreliable for more than a few kB, so saving all
but tiny files regularly hangs. Maybe the ssh tunnel to the outer
world is defective or constrained, but I have no control over this
aspect :-( A patch-based save would work for me, as I tend to save WIP
files often, so the patches are very small.

2) I have observed that 'M-x compile' will remotely run my (e.g.) make
command. This is wonderful, and I became even more astonished seeing
that clicking in compile errors in .c files even opens the remote file
and positions the cursor. But sometimes the error parser gets confused
and does not chop off the ":line:column" portion from the filename and
tries to open e.g. 'foo.c:77:23', which - of course - does not exist.
Is this a tramp-related problem? (I guess so, since locally all is
good.)

That's it, thanks for any hints in advance!

Cheers,

    Gabor
