cmdutil: handle multiline translations of HG: messages safely Before this, if a localizer/localization included a multiline message, and didn't prefix the intermediate lines with 'HG: ', then the line would be a candidate for inclusion in the commit message -- which isn't ideal.

strip: compress bundle2 backup using BZ Storing uncompressed bundle on disk would be a regression. Strip backup using bundle2 are now compressed when requested.

writebundle: add a compression argument for the bundle2 case Bundle2 compression is more complex than the bundle1 one. Therefore it is handled by the bundler itself. Moreover, on-disk bundle2 will probably have a large number of flavors so simply adding a new "format" for it does not seems the way to go. This will be used in the next changeset to compress bundle2 strip backup.

strip: use bundle2 + cg2 by default when repository use general delta The bundle10 format (plain changegroup-01) does not support general delta and result into expensive delta re-computation when stripping. If the repository is general delta, we store backups as bundle20 containing a changegroup-02 payload. We remove the experimental feature related to strip backup bundle format because this achieve the same goal in a leaner way. Removing the experimental option is fine, that is why it experimental in the first place. Compression of these bundles are coming in later changesets.
