graphmod: shorten graph

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    1035 Merge with BOS
|\
| o  1034 Fix help output, and a few broken tests.
| |
| o    1033 Merge with MPM.
| |\
| | o  1032 Get patchbomb working with tip again.
| | |
| | o  1031 Rewrite log command.  New version is faster and more featureful.
| | |
| | o    1030 Merge with MPM.
| | |\
| | | o  1029 Emacs: implement hg-incoming, hg-outgoing and hg-push.
| | | |
| | | o  1028 Add commands.debugconfig.
| | | |
| | | o  1027 Emacs: fix up hg-log and hg-diff to operate more uniformly.
| | | |
| | | o    1026 Merge with MPM.
| | | |\
| | | | o  1025 Merge with MPM.
| | | | |
| | | | ~
| | | o  1024 Sync buffers prior to doing a diff.
| | | |
| | | ~
o | |  1023 Minor tweak to the revgen algorithm
|/ /
o |  1022 Minor hgwebdir tweaks
| |
o |  1021 Add Makefile to the manifest
| |
o |  1020 Add default make rule
| |
o |  1019 Create helper functions for I/O to files in the working directory
| |
o |  1018 Add some aliases
