changegroup: do not count closed new heads (issue2697) If a closed head gets pulled, we currently see (example): $ hg pull pulling from $TESTTMP/repo2 searching for changes adding changesets adding manifests adding file changes added 2 changesets with 1 changes to 1 files (+1 heads) (run 'hg heads' to see heads, 'hg merge' to merge) A subsequent 'hg heads' doesn't show that head because it is closed. This patch improves the UI response texts for that same use case to: $ hg pull pulling from $TESTTMP/repo2 searching for changes adding changesets adding manifests adding file changes added 2 changesets with 1 changes to 1 files (run 'hg update' to get a working copy) That is, the part "(+1 heads)" is not shown in that case any longer.
