Update qimport help explaining how to read a patch from stdin (Issue371)

convert: Improved svn source detection.

strip: make repair.strip transactional to avoid repository corruption Uses a transaction instance from the local repository to journal the truncation of revlog files, such that if a strip only partially completes, hg recover will be able to finish the truncate of all the files. The potential unbundling of changes that have been backed up to be restored later will, in case of an error, have to be unbundled manually. The difference is that it will be possible to recover the repository state so the unbundle can actually succeed.

transaction: support multiple, separate transactions Solves that committed (closed) transactions may linger and be returned on subsequent transaction calls, even though a new transaction should be made, rather than a new nested transaction. This also fixes a race condition with the use of weakref.

transaction: only delete journal on successful abort/commit This solves that the journal file was always deleted when the transaction was deleted, no matter whether the abort (rollback) succeeded or not. Thus, never supporting a hg recover. The journal file is now only deleted on close (commit) or a successful abort.

i18n-de: synchronised with hg.pot

inotify: Do not raise TypeError when client.query returns None When something went wrong in client.query, it returns None. If inotify.debug=True, we will attempt in this case a zip(A, None, B), which would raise a TypeError.
