folding and creating no new change doesn't break:

-------------------------------------------------

folded content is dropped during a merge. The folded commit should properly disapear.

  $ mkdir fold-to-empty-test

  $ cd fold-to-empty-test

  $ hg init

  $ printf "1\n2\n3\n" > file

  $ hg add file

  $ hg commit -m '1+2+3'

  $ echo 4 >> file

  $ hg commit -m '+4'

  $ echo 5 >> file

  $ hg commit -m '+5'

  $ echo 6 >> file

There were conflicts, we keep P1 content. This

should effectively drop the changes from +6.

Test fold through dropped

-------------------------

Test corner case where folded revision is separated from its parent by a

dropped revision.

  $ hg commit -Am '1+2+3'
