Let me recap the problem, since it's been a while.  The problem was
that Tramp has a feature which requests auto-save files to be saved
locally.  But this feature led to auto-save filenames which triggered
jka-compr (if the original file was a compressed file), and
jka-compr-write-region does not want to be called with nil for START
and END, but auto_save_1 does just that.

I have now done the following:

First, Tramp converts the remote file name, for example


into a local file name, for example


Then, Tramp invokes make-auto-save-file-name on this file, leading to


And this correctly leads to jka-compr not being invoked, even if the
file was something like foo.gz.
