After the failed commit was the working copy locked, that's a
Subversion lock where 'svn st' shows state 'L'? 

In principle Subversion's log file mechanism should have meant that
the failed commit left the working copy locked.  However I think I see
a bug that would have unlocked the working copy.  Look at the
svn_wc_adm_close at the end of svn_client_commit, that will have the
effect of removing the lock even if an error occurred.  There is a
comment there (one I think I added when I did the access baton
conversion) questioning the logic.  I think the correct behaviour in
your case would be for the lock, and log file, to remain.  Then there
is a chance that 'svn cleanup' would have fixed the working copy.

I don't really understand why there is special 'cleanup:' handling in
svn_client_commit, I guess it is to ensure that a failed commit always
calls abort_edit.  Anyone know the history?  I think it is an error
both to remove the locks, and to clear the temporary files, if a
commit error occurs.

By "failed commit" I meant "'svn commit' producing an error".

I realised that, I thought I explained the failure mechanism in my
mail :-/

This wasn't actually a failed commit, I think.  As the messages 
announced, the commit itself worked, it was only the fix-up of the WC 
(and text-base) that choked.

This wasn't actually a failed commit, I think.  As the messages 
announced, the commit itself worked, it was only the fix-up of the WC 
(and text-base) that choked.
