parsers: allow nt_find to signal an ambiguous match

parsers: factor out radix tree initialization

parsers: update ntrev when we stop scanning This prevents us from inserting some nodes twice, wasting work.

tests: set a standard terminal type This makes test-ui-color.py happy when run in a dumb terminal. Spotted by Jesse Glick <jesse.glick@oracle.com>

branches: quiet option observes other parameters

build: fix hgrc manpage building with docutils 0.9 Since docutils 0.9, `roman` module has been moved from module directory root (i.e. `site-packages/roman.py`) to `docutils.utils` module. Therefore `import roman` statement should be wrapped in `try: ... except ImportError: ...` block to handle importing correctly.

context: fix call to util.safehasattr

alias: inherit command optionalrepo flag (issue3298) Commands working without a repository, like "init", are listed in commands.norepo. Commands optionally using a repository, like "showconfig", are listed in commands.optionalrepo. Command aliases were inheriting the former but not the latter.

tests: improve test of hg-ssh and make the test pass on windows
