Take kernel development for example, sub-maintainers not always keep
a patchset in a single branch, instead, there could be a mix of patchset
and single fixing patches on a same branch:

  ---A1---A2---A3---B---C---D---E1---E2---E3---E4---F---G---H---> branch

When we identify a specific patch, e.g. E3, is it possible to figure out
the whole patchset of E<n>?
