copy-tracing: test case where a merge reverted a file deletion

This case is currently broken for commit centric copy tracing. So we add an
official case for it with a note about it being broken.

Fixing it will requires multiples change in code related to merge, commit and
copy tracing, so we introduce it beforehand for simplicity.

Also, I have been sitting on this test for 3 months so I would rather have it
upstream.

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

from __future__ import absolute_import

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!')

    webcommands.__all__.append(b'raiseerror')
