histedit: use better meta-variable names than VALUE in help text

Before this change hg help histedit would use the default variable label:

    --commands VALUE
...
 -r --rev VALUE [+]

With this change the text will be in the usual help text style and a bit more
explanatory:

    --commands FILE
...
 -r --rev REV [+]

# 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')
