dispatch: only check compatibility against major and minor versions (BC)
Extensions can declare compatibility with Mercurial versions. If an
error occurs, Mercurial will attempt to pin blame on an extension that
isn't marked as compatible.
While all bets are off when it comes to the internal API, my experience
has shown that a monthly/patch release of Mercurial has never broken any
of the extensions I've written. I think that expecting extensions to
declare compatibility with every patch release of Mercurial is asking a
bit much and adds little to no value.
This patch changes the blame logic from exact version matching to only
match on the major and minor Mercurial versions. This means that
extensions only need to mark themselves as compatible with the major,
quarterly releases and not the monthly ones in order to stay current and
avoid what is almost certainly unfair blame. This will mean less work
for extension authors and almost certainly fewer false positives in the
blame attribution.
