Move ellipsis code to util.ellipsis() and improve maxlength handling.

Use UnexpectedOutput exception instead of RepoError in sshrepo, too.

Change sshrepo.repoerror() into a more flexible sshrepo.raise_(). Now every exception can be raised with a cleanup, not only hg.RepoError.

Don't show traceback on 'hg clone -r unknown ssh://hg.example.com/'.

fix qseries -v and guards interaction - rename "status" variable to avoid shadowing an argument - use a better test to determine whether a patch is applied

changegroup.py: delay the loading of the bz2 and zlib modules

Ignore all errors while parsing the branch cache.

small fixes for test-newbranch - hg tip doesn't use the branch cache; use hg log -r in its place - commit doesn't use a HG_MERGE environment variable - change the dates from "0 0" to "1000000 0"

transplant: split filter args into changelog entry and patch

transplant: log source node when recovering too.

transplant: clobber old series when transplant fails

Use unsigned version format. This way can use one additional bit, and when encountering invalid revlogs with the first bit set don't produce python warnings or strange error messages.

Improve error message for unknown revlog flags. Old: unknown flags 120000 for ... New: unknown flags 0x0012 for ...

transplant: "filtering %s\n"

Don't require a diff which accepts the -N option.

Compatibility fix for 'ln -sf'. ln of Solaris 8 only accepts "ln -f -s" (in that order), but as the -f isn't needed here, I simply dropped it.

additional fixes for issue436

Fix test-rename-dir-merge for different implementations of ls.

Fix test-notify for systems without or with a different version of diffstat. Some diffstat versions say "1 file changed", others "1 files changed".
