route: scm: add revision requirements for git/mercurial branches (#10026)

hgsubversion mirror (https://bitbucket.org/redmine/redmine-all) has
"../sandbox/rails-2.3" and "../sandbox/rails-2.2" *named* branches.

"View revisions" link of "../sandbox/rails-2.3" generates
"repository/revisions/..%2Fsandbox%2Frails-2.3/changes".
But, passenger returns "Not Found".
