run-tests: add "debug" mode: don't capture child output, just show it. In debug mode, we: - don't try to diff expected vs actual output - disallow --interactive - disable timeouts (warn if user tried to supply one) - don't try to parse hghave output, since we don't have the output - don't try to save output to .err file

run-tests: make --tmpdir option more useful. - instead of creating HGTMP inside tmpdir, now HGTMP is tmpdir (thus, fail if tmpdir already exists) - passing --tmpdir automatically turns on --keep-tmpdir

hg.1: kill spurious backslash I believe the backslash prevented asciidoc from automatically turning "(C)" into a real copyright symbol. This replacement is not done in reST in the first place.

help: markup email addresses as inline literals Otherwise we get useless links to user@example.org in the HTML version of the man pages.

doc/Makefile: add help/*.txt as a dependency

doc: add some internal links to man pages

hgrc.5: combined short paragraphs into one Short and precise sentences are good, but we can have more than one such sentence per paragraph.

doc: use reST note directive The 'NOTE: bla bla' syntax was for asciidoc and is still present in a couple of docstrings. The docstrings will be converted to reST format when minirst knows how to handle it.

hgrc.5: capitalize True and False consistently

commands: slightly better help for --traceback
