Pager extension: switch it off if --debugger is set The pager is preventing the debugger prompt and much of the debugger output to be refreshed. Moreover the pager does not make sense when debugging line by line. (This supersedes the similar ui.debugflag patch. Disabling the pager for debug output doesn't make that much sense, as this is actually when the pager might be useful.)

rollback: unlink files truncated to length 0

make test-diff-copy-depth executable

convert: fix test-convert-svn-* problems with mtime not changing The `svn commit` command does not detect changed files unless their mtime has changed. A quick succession of, for instance, `svn co ...; echo x >> y; svn ci` can thus lead to the change to y being ignored. Edited by pmezard to write in binary mode.

copies: refactor symmetricdifference as _findlimit We only need to track the lowest revision seen, which makes things simpler.

copies: teach symmetric difference about working revisions - use changelog.count() as a pseudo revision number - abort early in copies if revs are the same - eliminate working dir hacks in copies - yield results as they're found

symmetricdifference: move back to copies It's too tightly dependent on known revlog ordering to fit well in ancestors
