fix: refactor getrevstofix() to define revisions first, then validate them
This refactoring makes it easier to add a new way of specifying
revisions (I'm about to add a `--source`, which adds the specified
revisions and their descendants).
Differential Revision: https://phab.mercurial-scm.org/D8285
# See http://EditorConfig.org for the specification
