narrow: don't send the changelog information when widening without ellipses
When we widen anon-ellipses narrow copy, the server sends the changelog
information of all the changesets. The code was copied from ellipses case and in
ellipses cases, it's required to send the new changelog data.
But in non-ellipses cases, we don't need to send the changelog data as we will
have all the changesets locally.
Before this patch, there was a overhead of ~8-10 mins on each widening call
because of all the changelog information being pulled and being applied. After
this patch, we no more pull the changelog information. So this patch can save ~5
mins on Mozilla repo on each widening and more on repos which have more
changesets.
When we apply an empty changelog from changegroup, there is a devel-warn. This
patch kind of hacks to silence that devel-warn.

'''http authentication with factotum This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access. Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully supported. If no prefix is specified, a value of "*" will be assumed. By default, keys are specified as:: proto=pass service=hg prefix=<prefix> user=<username> !password=<password> If the factotum extension is unable to read the required key, one will be requested interactively. A configuration section is available to customize runtime behavior. By default, these entries are:: [factotum] executable = /bin/auth/factotum mountpoint = /mnt/factotum service = hg The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service. Lastly, the service entry controls the service name used when reading keys.
