revset: replace parsing alias definition by _parsealiasdefn to parse strictly Before this patch, referring alias arguments is parsed by string base operation "str.replace". This causes problems below (see the previous patch introducing "_parsealiasdefn" for detail) - the shorter name argument breaks referring the longer name - argument names in the quoted string are broken This patch replaces parsing alias definition by "_parsealiasdefn" to parse strictly.

revset: introduce _parsealiasdefn to parse alias definitions strictly This patch introduces "_parsealiasdefn" to parse alias definitions strictly. For example, it can avoid problems below, which current implementation can't. - the shorter name argument breaks referring the longer name one in the definition, if the former is completely prefix of the latter for example, the alias definition "foo($1, $10) = $1 or $10" is parsed as "_aliasarg('$1') or _aliasarg('$1')0" and causes parse error, because tail "0" of "_aliasarg('$1')0" is invalid. - argument names in the quoted string are broken for example, the definition "foo($1) = $1 or desc('$1')" is parsed as "_aliasarg('$1') or desc('_aliasarg(\'$1\')')" and causes unexpected description matching against not '$1' but '_aliasarg(\'$1\')'. To decrease complication of patch, current implementation for alias definitions is replaced by "_parsealiasdefn" in the subsequent patch. This patch just introduces it. This patch defines "_parsealiasdefn" not as a method of "revsetalias" class but as a one of "revset" module, because of ease of testing by doctest.

hgweb: use revset.spanset where appropriate It is remainder of 9ad6dae67845 where spanset was introduced.

subrepo: add 'cat' support for git subrepos V2: use 'self._ctx.node()' instead of 'rev' in makefileobj. As Matt Harbison mentioned, using 'rev' does not make sense, since we'd be passing a git revision to the top-level Mercurial repository.
