largefiles: don't prompt for normal/largefile changes when doing plain updates

We used to get like:

  $ hg up -r 2
  foo has been turned into a normal file
  keep as (l)argefile or use (n)ormal file? l
  getting changed largefiles
  0 largefiles updated, 0 removed
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ cat foo
  cat: foo: No such file or directory
  [1]

- which both asked the wrong question and did the wrong thing.

Instead, skip this conflict resolution when the local conflicting file has been
scheduled for removal and there thus is no conflict.

'''expand expressions into changelog and summaries

This extension allows the use of a special syntax in summaries, which
will be automatically expanded into links or any other arbitrary
expression, much like InterWiki does.

A few example patterns (link to bug tracking, etc.) that may be used
in your hgrc::

  [interhg]
  issues = s!issue(\\d+)!<a href="http://bts/issue\\1">issue\\1</a>!
  bugzilla = s!((?:bug|b=|(?=#?\\d{4,}))(?:\\s*#?)(\\d+))!<a..=\\2">\\1</a>!i
  boldify = s!(^|\\s)#(\\d+)\\b! <b>#\\2</b>!
