Named Branches Lost on hg convert.

Dear Tom,
For what it is worth, I have created a version of hg convert that takes
a --rev-all-branches REV option. This basically will convert _all
revisions_ up to REV, not just those on the same branch as REV.
If you subsequently sort by sourcesort, your truncated repository will
look exactly the same as the original up to REV.
It barfs if you specify both --rev and --rev-all-branches.
Internally I am passing a "get_opts" parameter into
converter_source::getheads that indicates whether to do the "get all" or
regular "get". I of course only use that parameter in
mercurial_source::get_heads, but I propagated it to all the other source
converters should anyone want (and be able) to implement similar
behavior in other sources.
This is all available at
https://bitbucket.org/TomUdale/myhg/
along with my earlier additions to the eol extension.
Thanks for all your help.
All the best,
Tom
