revisionbranchcache: fall back to slow path if starting readonly (issue4531)...
revisionbranchcache: fall back to slow path if starting readonly (issue4531) Transitioning to Mercurial versions with revision branch cache could be slow as long as all operations were readonly (revset queries) and the cache would be populated but not written back. Instead, fall back to using the consistently slow path when readonly and the cache doesn't exist yet. That avoids the overhead of populating the cache without writing it back. If not readonly, it will still populate all missing entries initially. That avoids repeated writing of the cache file with small updates, and it also makes sure a fully populated cache available for the readonly operations.

Test to make sure folding renames doesn't cause bogus conflicts (issue4251):
$ hg init issue4251
$ cd issue4251
$ mkdir initial-dir
$ echo foo > initial-dir/initial-file
$ hg add initial-dir/initial-file
$ hg commit -m "initial commit"
Move the file to a new directory, and in the same commit, change its content:
$ mkdir another-dir
$ hg mv initial-dir/initial-file another-dir/
$ echo changed > another-dir/initial-file
$ hg commit -m "moved and changed"
Rename the file:
$ hg mv another-dir/initial-file another-dir/renamed-file
$ hg commit -m "renamed"
Now, let's try to fold the second commit into the first:
$ cat > editor.sh <<EOF
