24.2; vc-diff from vc-log doesn't show diff before renames (for Mercurial backend). |

As always:
$ emacs -Q
Next I open any file from Mercurial repo which is "hg mv" or "hg cp".
If you build history "C-x v l" and try to look diff (log-view-diff or "d") for
changeset before rename you get message, like:
Finding changes in /home/user/devel/my-devel/gadict/en-pronunciation_ru.rst...
No changes between 214 and 215
while:
$ hg diff -r 215 en-pronunciation_ru.rst
diff --git a/en-spelling_ru.rst b/en-pronunciation_ru.rst
copy from en-spelling_ru.rst
copy to en-pronunciation_ru.rst

I expect that vc-view-diff follow history on copy as this do original CLI
client "hg".

Sorry, I didn't read properly. You were talking about calling "diff"
from a log buffer. I still think using log -f may help, since otherwise
it presumably looks like there is nothing to take a diff of. Does it
help?
Answering my own question, no.
But what does
hg diff -r 214 -r 215 en-pronunciation_ru.rst
report for you?
For me, an equivalent diff command does not report any differences.
So this looks like an hg issue, not an Emacs one.
It can be called an Hg issue, but it resembles Git in this: both 'diff'
and 'blame' commands require the file names that feature in the revision
asked about, not the "current" ones.
In the course of fixing bug#55871, I've also added Hg support, so now
you should have a button at the end of the revision history, if the last
commit contains renames, to show the log for the previous name(s).
Note that for this to work, "-f" should _not_ be in vc-hg-log-switches.
Closing, but feedback welcome.
