help: describe about choice of :prompt as a fallback merge tool explicitly

"merge-tools" help topic has described that the merge of the file
fails if no tool is found to merge binary or symlink, since
c77f6276c9e7 (or Mercurial 1.7), which based on (already removed)
MergeProgram wiki page.

But even at that revision, and of course now, merge of the file
doesn't fail automatically for binary/symlink. ":prompt" (or
equivalent logic) is used, if there is no appropriate tool
configuration for binary/symlink.

====================================
Testing head checking code: Case B-2
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category B: simple case involving pruned changesets
TestCase 2: multi-changeset branch, head is pruned, rest is superceeded

.. * 2 changeset branch

.. new-state:
