svn subrepo: attempt work around obstructed checkouts (issue2752) It should be possible to do better than this with 'svn switch', but the logic required woud be significantly more complex. Until someone needs the performance improvements of using switch, we'll just use the same strategy for everything.

churn: strip key earlier to avoid false negative seach in aliases

bookmarks: further restrict IOError on write This won't risk losing the undo file when the error was something other than file not found

tags: loosen IOError filtering when reading localtags

run-tests: don't count test as succeeded if it failed regressed around ec4ae5727f07

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.
