$ strip '1:'
The branchmap cache is not adjusted on strip.
Now mentions a changelog entry that has been stripped.
$ cat .hg/cache/branch2-visible

$ commit c
Not adjusted on commit, either.

On pull we end up with the same tip, and so wrongly reuse the invalid cache and crash.
$ hg pull ../repo 2>&1 | grep 'ValueError:'
ValueError: node a3498d6e39376d2456425dd8c692367bdbf00fa2 does not exist (known-bad-output !)
