branchcache: do not accept "empty update"

This currently does not happens and it will be simpler that is remains that way.
If all update do something, we will be able to simply declare, in a later
changesets, that all update to result in a dirty branchcache.

= Mercurial 6.6.3 =

 * tests: don't use "status" operand of dd in test-censor.t (issue6858)
 * tests: make sha256line.py available for all tests
 * tests: use sha256line.py instead of /dev/random in test-censor.t (issue6858)
 * tests: fix nondeterministic test failure in test-contrib-perf.t
 * rust-changelog: don't panic on empty file lists
 * grep: restore usage of --include/--exclude options

 = Mercurial 6.6.2 =

 * histedit: remove superfluous echo() and endwin() calls (issue6859)
 * persistent-nodemap: avoid writing nodemap for empty revlog
 * persistent-nodemap: respect the mmap setting when refreshing data
 * bundle: do not detect --base argument that match nothing as lack of argument
 * narrow: prevent removal of ACL-defined excludes
 * pycompat: fix bytestr(bytes) in Python 3.11

= Mercurial 6.6.1 =

The first two patches fix aborted transactions that could happen since 6.6.

 * revlog: avoid exposing delayed index entry too widely in non-inline revlog
 * revlog: avoid wrongly updating the data file location on "divert"
 * tests: do not fail tests in a state with uncommitted .py file removal
 * perf-tags: fix the --clear-fnode-cache-rev code
 * perf-tags: fix clear_cache_fnodes to actually clear that cache
 * censor: fix things around inlining
 * Various Python 3 cleanups
 * Various Windows test suite fixes

= Mercurial 6.6 =

As usual, a *lot* of patches don't make it to this list.
