highlight: support annotate, and reduce layering violations.

Introduce templateopts and logopts to reduce duplicate option definitions.

Add option -l/--limit to hg incoming and hg outgoing.

Move finding/checking the log limit to cmdutil

Make hg debugancestor accept -R by making it an optionalrepo command.

debugancestor: use *args instead of *opts, to not confuse with option dicts.

mq: Cleanup: update outdated file header.

convert: Clean up authormap key=value splitting. Introduces a subtle parsing difference: dstauthor can now contain '=' characters.

convert: Avoid redundant newline on authormap errors. The extra rstrip is necessary in case the file has uses different line terminators (i.e. CRLF).

convert: Ignore empty lines in authormap file.

Add config option to disable putting .hg_archival.txt inside archives.

add a blame alias for annotate The original cvs command was called blame. SVN has both, and other VC systems typically also have this as an alias. Makes things easier for converts.

warning on push should mention heads, not branches This makes the concept easier to relate to similar messages given on pull, and allows for a distinction between heads and (named) branches.

commands: lock() the repo while unbundling (issue1004)

patch: fix iterhunks() with trailing binary file removal Like some renames or copy operations, binary file removal does not generate any "file" or "hunk" action, but was not tagged as such and let iterhunk() assume no hunk was applied for the deleted file.
