Interesting.  I can reproduce this in a new repository that contains
just these two entries, but if I go to one of my usual working copies and
modify some files, those files do get offered by the completion.

Okay, but note that 'diff' and 'log' would be expected to complete
different things.  'diff' tries to complete only files with local mods;
'log' should complete only filenames that exist on the server.  For example:

Status	diff?	log?
------	-----	----
A	yes	no
M	yes	yes
<space>	no	yes

As I said in my previous email, simply using _files wouldn't complete
everything that should be completed: files with status '!' or 'D', or
files with 'Depth: exclude', for example.

This sounds right, though the machinery currently in there
(_call_program, cache) should be added back.  Calling 'svn st foo' for
each file individually would be slow.  Also, a '--' should be added.

Not sure.  What about conflicted files?  Unmodified files in a
changelist?  Unmodified files that were locked by another working copy?

What about completing foo/bar after «svn rm foo»?

Thanks a lot for working on this.  Let's try to break this into small,
incremental improvements.

You sent the diff reversed: the file as in HEAD of master should be the
first argument to diff.  Also, for bonus points, send the diff with a
.txt extension and not compressed.  (Doing so gives it a text/* MIME
type, which makes the diff easier to read on our end.)
