Behaviour of log --patch --follow

[ekhumoro]

Hello

With mercurial version 3.3.3 and earlier, I could use the following to 
get a diff for a specific revision that follows history across copies 
and renames:

     hg log --patch --follow -r 233

However, when I try this with mercurial-3.4, it dumps a diff for a 
random file from every changeset back to the beginning of the history. 
If I omit the --follow option, I do get a diff for a single revision, 
but of course it doesn't follow history.

What am I doing wrong?
