rust-index: optimize find_gca_candidates() on less than 8 revisions
This is expected to be by far the most common case, given that, e.g.,
merging involves using it on two revisions.
Using a `u8` as support for the bitset obviously divides the amount of
RAM needed by 8. To state the obvious, on a repository with 10 million
changesets, this spares 70MB. It is also possible that it'd be slightly
faster, because it is easier to allocate and provides better cache locality.
It is possible that some exhaustive listing of the traits implemented by
`u8` and `u64` would avoid the added duplication, but that can be done later
and would need a replacement for the `MAX` consts.
"""strip changesets and their descendants from history (DEPRECATED)
The functionality of this extension has been included in core Mercurial
since version 5.7. Please use :hg:`debugstrip ...` instead.
This extension allows you to strip changesets and all their descendants from the
repository. See the command help for details.
