subrepo: handle svn tracked/unknown directory collisions This happens more often than expected. Say you have an svn subrepository with python code. Python would have generated unknown .pyc files. Now, you rebase this setup on a revision where a directory containing python code does not exist. Subversion is first asked to remove this directory when updating, but will not because it contains untracked items. Then it will have to bring back the directory after the merge but will fail because it now collides with an untracked directory. Using --force is not very elegant and only works with svn >= 1.5 but the only alternative I can think of is to write our own purge command for subversion.

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).
