revset: map postfix '%' to only() to optimize operand recursively (issue4670)

Instead of keeping 'onlypost' as a method, this patch rewrites it to 'only'
function. This way, 'x%' always has the same weight as 'only(x)'.

# A dummy extension that installs an hgweb command that throws an Exception.

from mercurial.hgweb import webcommands

def raiseerror(web, req, tmpl):
    '''Dummy web command that raises an uncaught Exception.'''

    # Simulate an error after partial response.
    if 'partialresponse' in req.form:
        req.respond(200, 'text/plain')
        req.write('partial content\n')

    raise AttributeError('I am an uncaught error!')

def extsetup(ui):
    setattr(webcommands, 'raiseerror', raiseerror)
    webcommands.__all__.append('raiseerror')
