Oh! Thanks for the explanation.
I've pushed the patch now, thanks to OP again, closing.
[Message part 3 (message/rfc822, inline)]
Opening a file version-controlled under mercurial causes the following
error:
vc-hg--requirements-understood-p: Symbol’s function definition is void:
cl-set-difference
And the file is not opened.
Reproduction steps:
$ emacs -Q -file <a-hg-controlled-file>
In `vc-hg.el' `cl-lib' is required in compile time. Requiring it in
evaluation seems to fix the problem. Below is the patch that fixes the
problem.
