   (run 'hg heads' to see all heads)
   [255]
   $ hg up -C default

 Implicit merge with default branch as parent:
 
   $ hg merge
   abort: branch 'default' has 3 heads - please merge with an explicit rev
   (run 'hg heads .' to see heads)
   [255]
 
 3 branch heads, explicit merge required:

   1 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (branch merge, don't forget to commit)
   $ hg ci -m merge
 
 2 branch heads, implicit merge works:
 
   $ hg merge
