wireproto: add test for new optional arg missing on server New argument is silently ignored by both HTTP and SSH servers. This means we can, for instance, add new flags to getbundle() to request advanced features (like lightweight-copy-aware bundles), and older servers will silently ignore this request and send back a plain bundle.

web: Made elapsed time calculation dynamic (javascript). This allow safe caching of the pages by the browser and still display the right amount of elapsed time upon page refresh. If javascript is disabled, absolute time is displayed, leaving it readable. All the templates have been updated.

extdiff: add repository root as a variable Some external diff tools (notably Plan 9 diff(1)) require the absolute path to the file being diffed for proper function. A root variable was added to inform an external tool of the repository root (the tool is invoked with the cwd set to tmproot).

help: move hgignore man page into built-in help (issue2769)

graphlog: make use of graphmod's revset support

graphmod: use revsets internally Thanks for the idea and most of the implementation to Klaus Koch Backs revisions() and filerevs() with DAG walker which can iterate through arbitrary list of revisions instead of strict one by one iteration from start to stop. When a gap occurs in a revisions (i.e. in file log), the next topological parent within the revset is searched and the connection to it is printed in the ascii graph. File graph can draw sometimes more connections than previous version, because graph is produced according to the revset, not according to a file's filelog. In case the graph contains several branches where the left parent is null, the graphs for each are printed sequentially, not in parallel as it was a case earlier (see for example the graph for README in hg-dev).
