Some suggestions:
- The parent description line needs to be quoted, or otherwise highlighted.
  As commit comments usually starts by a keyword and a colon, the single
  leading space is not sufficient to limit the confusion
- add " file(s)" at the end of the commit line, as David Soria Parra suggested
- use "up-to-date" instead of "(current)". Why do you use parenthesis here ?
  parenthesis could be reserved to suggest command to be used.
- use "newer changesets" instead of "new changesets". I mean those might not
  be brand new cset coming from a pull or commit, but due to shuffling with
  "update"
- may be use a separate line for suggested command. For example, the use of
  resolve for interrupted merge is not explicitly covered in summary.

Anyway, hg summary is a very good thing.

Gilles.
