log: do not --follow file that is deleted and recreated later (issue732)

== What ==

issue732 is only one example of a buggy behaviour, but there are in fact many
intricated cases. For example:

( "o" contains an alive version of the tracked file, "x" does not)

tip - o - o - x - o - o - x ...
   \
    o - o - o - o - x ...
     \     /
      o - o

This repository contains at least two instances of the tracked file, but
when calling "hg log -f file" only the latest one (the one alive in tip)
matters to us.

== How ==

We must extract from the filelog the history of the file instance we're
interested in and discard changes related to other instances of that file.

We see that we're only interested in ancestors(node), and that all
other nodes in the filelog should not be considered.

  $ hg help mq
  mq extension - manage a stack of patches
  
  This extension lets you work with a stack of patches in a Mercurial
  repository. It manages two stacks of patches - all known patches, and applied
  patches (subset of known patches).
  
  Known patches are represented as patch files in the .hg/patches directory.
  Applied patches are both patch files and changesets.
  
  Common tasks (use "hg help command" for more details):
  
    create new patch                          qnew
    import existing patch                     qimport
  
    print patch series                        qseries
    print applied patches                     qapplied
  
    add known patch to applied stack          qpush
    remove patch from applied stack           qpop
    refresh contents of top applied patch     qrefresh
  
  By default, mq will automatically use git patches when required to avoid
  losing file mode changes, copy records, binary files or empty files creations
  or deletions. This behaviour can be configured with:
  
    [mq]
    git = auto/keep/yes/no
  
  If set to 'keep', mq will obey the [diff] section configuration while
  preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq
  will override the [diff] section and always generate git or regular patches,
  possibly losing data in the second case.
  
  You will by default be managing a patch queue named "patches". You can create
  other, independent patch queues with the "hg qqueue" command.
  
  list of commands:
  
   qapplied     print the patches already applied
   qclone       clone main and patch repository at same time
   qdelete      remove patches from queue
   qdiff        diff of the current patch and subsequent modifications
   qfinish      move applied patches into repository history
   qfold        fold the named patches into the current patch
   qgoto        push or pop patches until named patch is at top of stack
   qguard       set or print guards for a patch
   qheader      print the header of the topmost or specified patch
   qimport      import a patch
   qnew         create a new patch
   qnext        print the name of the next patch
   qpop         pop the current patch off the stack
   qprev        print the name of the previous patch
   qpush        push the next patch onto the stack
   qqueue       manage multiple patch queues
   qrefresh     update the current patch
   qrename      rename a patch
   qselect      set or print guarded patches to push
   qseries      print the entire series file
   qtop         print the name of the current patch
   qunapplied   print the patches not yet applied
   strip        strip changesets and all their descendants from the repository
