Tool selection

default is internal merge:

  $ beforemerge

  [merge-tools]

  # hg update -C 1

hg merge -r 2

override $PATH to ensure hgmerge not visible; use $PYTHON in case we're

running from a devel copy, not a temp installation

  $ PATH="$BINDIR" $PYTHON "$BINDIR"/hg merge -r 2

  merging f

  warning: conflicts during merge.

  merging f incomplete! (edit conflicts, then use 'hg resolve --mark')

  0 files updated, 0 files merged, 0 files removed, 1 files unresolved

  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
