paper: break long lines in map file

hgwebdir: refresh configuration periodically The old default behaviour of hgwebdir was to maintain a list of repositories permanently. This interacted badly with persistent application hosting software such as WSGI containers. If a new repository was published, it would potentially never appear in the top-level list of repositories. This change causes the hgwebdir configuration and list of repositories served to be refreshed periodically (at most every 20 seconds).

allow toggling when the cursor is on the correct line instead of just the filename text in hg-commit-toggle-file

coal/paper: Wrap diff in <pre/> In text-mode browsers the diff is otherwise rendered as just one long line per file. Other styles do the same.

some modernization cleanups, forward compatibility

Makefile: fix grammar in comment

windows: avoid deleting non-empty reparse points If a hg repository including working directory is a reparse point (directory symlinked or a junction point), then using os.removedirs will remove the reparse point erroneously. This is fixed by only removing directories if they are empty.

transaction: add atomic groups to transaction logic When performing a strip operation on a repository, it is vital that all the truncations are performed, or that none of them are. This is done by adding support for writing a number of entries in a single operation. Co-contributor: Sune Foldager <cryo@cyanite.org>
