tags: visit new heads in forward order when rebuilding cache This improves performance of building the tag cache by 4x on a repo with ~2800 heads.

identity: show trailing '+' for dirty subrepos (issue2839)

discovery: fix invalid comment about extinct being ignored

obsolete: fix decoding error message arguments

push: do not try to push remote obsolete if local has none

help: fix some instances of 'the the'

pager: work around bug in python 2.4's subprocess module (issue3533) hg v2.2.2 fixed the pager on Windows, but broke it on Python 2.4. This patch only uses the new behavior if Python >= 2.5 is detected.

clone: copy obsolete markers during local clone This change adds `obsstore` to the list of files copied by local clone, until now changesets were copied without their obsolete markers. Note: extinct changesets were and are still included by such clones to enable hardlinking. There is no obvious reason to prevent their exchange here. Rebased by Patrick Mezard <patrick@mezard.eu>
