D9955: build: fake PEP440 versions

[joerg.sonnenberger (Joerg Sonnenberger)]

joerg.sonnenberger created this revision.
Herald added a reviewer: hg-reviewers.
Herald added a subscriber: mercurial-patches.

REVISION SUMMARY
  If the current version is not exactly a tag, use a local version
  specifier to fix it up. PEP 440 uses the "+" separator and only allows
  alphanumeric and dot, so use dot for further separations.

REPOSITORY
