Bert Wesarg[TopGit PATCH] prev/next/tsort: commands to explore dependencies
I hacked 3 commands to explore the dependencies of TopGit patches:
I) tg prev [NAME]
outputs the dependencies of NAME II) tg next [NAME]
outputs patches that depends on NAMEIII) tg tsort [PATTERN]
outputs a topological order of all patches starting with PATTERNI'm more than open for improvments.
