uncommit: abort if an explicitly given file cannot be uncommitted (BC)

I've gotten burned several times by this in the last few days.  The former tests
look simple enough, but if a good file and a bad file are given, the bad files
are silently ignored.  Some commands like `forget` will warn about bogus files,
but that would likely get lost in the noise of an interactive uncommit.  The
commit command aborts if a bad file is given, so this seems more consistent for
commands that alter the repository.

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

from __future__ import absolute_import

from mercurial.hgweb import (
    webcommands,
)

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

    # Simulate an error after partial response.
    if b'partialresponse' in web.req.qsparams:
        web.res.status = b'200 Script output follows'
        web.res.headers[b'Content-Type'] = b'text/plain'
        web.res.setbodywillwrite()
        list(web.res.sendresponse())
        web.res.getbodyfile().write(b'partial content\n')

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

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