mq: add --currentuser and --user options to qnew and qrefresh These options make qnew and qrefresh add/update the "From:" header (or, if present, the "# User" header). This allows proper attribution of patches in patch queues with multiple contributors.

Tests for b5605d88dc27 and 840e2b315c1f (interactive prompts during merge)

Make ui.prompt repeat on "unrecognized response" again (issue897) (this was accidentally changed in ca0d02222d6a)

Fix misleading error and prompts during update/merge (issue556)

patch: be more tolerant to diffstat failures (issue 865) Sometimes, revisions cannot be represented by a regular diff, only a git diff would capture binary files or permission changes. diffstat cannot handle git patches and will output "0 files changed" when fed with an empty diff. We cannot consider the latter to be an error, unless we rewrite diffstat to handle these correctly.

Fix chmod of writable but unowned files (issue530) This could happen e.g. in group writable local repositories where a file should become executable on update. (Patch by Benoit Boissinot attached to issue530)

Fix test-convert-darcs output on Debian etch (issue779) The CR characters of darcs get confused the output. Additionally this darcs version printed: darcs: <stdin>: hGetLine: end of file
