Basic tests

===========

(no criss cross merge)

Smoke tests

-----------

Starts with a "simple case"

  $ hg init repo_A

  $ cd repo_A

  $ hg debugbuilddag '

  > ..:g   # 2 nodes, tagged "g"

  > <2.:h   # another node base one -2 -> 0, tagged "h"

  > *1/2:m # merge -1 and -2 (1, 2), tagged "m"

  > <2+2:i # 2 nodes based on -2, tag head as "i"

  > .:c    # 1 node tagged "c"

  > <m+3:a # 3 nodes base on the "m" tag

  > <2.:b  # 1 node based on -2; tagged "b"

  > <m+2:d # 2 nodes from "m" tagged "d"

  > <2.:e  # 1 node based on -2, tagged "e"

  > <m+1:f # 1 node based on "m" tagged "f"

  > <i/f   # merge "i" and "f"

  > '
