Shorten the graph, cutting the all vertical (not oblique) edges rows.
Activate with 'graphshorten = true' in [experimental] section.

Example graph with deactivated option:

$ hg log --graph --template '{rev} {desc|firstline}' --rev 1035:1015

| |
| o    1033 Merge with MPM.
| |\
| | o  1032 Get patchbomb working with tip again.
