# Make sure that the internal merge tools (internal:fail, internal:local, and

# internal:other) are used when matched by a merge-pattern in hgrc

Make sure HGMERGE doesn't interfere with the test:

  $ unset HGMERGE

  $ hg init

  $ echo "line 1" > f

  $ echo "line 2" >> f

  $ echo "line 3" >> f

  $ hg ci -Am "revision 0"

  adding f

  $ cat f

Branch 1: editing line 1:

  $ sed 's/line 1/first line/' f > f.new

  $ mv f.new f

  $ hg ci -Am "edited first line"

Branch 2: editing line 3:

  $ hg update 0

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

  $ sed 's/line 3/third line/' f > f.new

  $ mv f.new f

  $ hg ci -Am "edited third line"
