GNU folks even managed to insert text that allows a completely empty
line (not a line with a single SP on it) to express a context line
that is empty, which means...

Really? That's a surprise for me. What I can tell for sure, Emacs' diff
mode doesn't support this, as it does interpret plain empty line as a
hunk delimiter, at least in Emacs 22.1.

See b507b465f7831612b9d9fc643e3e5218b64e5bfa (git-apply: prepare for
upcoming GNU diff -u format change).  Around the time that eventually
lead to this commit (mid October 2006) there was a discussion on this
mailing list on the issue, too.  I do not doubt you checked with your
version of Emacs diff mode that it does not support this yet, but it's
only prudent to assume that a new version someday will.

Thanks, -- it was interesting to read corresponding discussions.

Due to this change in GNU diff, it seems that empty line is indeed a
wrong choice for syntactic hunk separator :( I wonder if there is a
common way to say "here the patch ends" then[1]? My best guess is that

will do.

[1] I've checked bzr and hg. Bzr uses empty line for that (followed by
"# Begin bundle" line) in their "merge directive" format. Not
Emacs-friendly either :( Hg's "export" just EOFs after the patch.
