[TopGit PATCH 4/6] tg-prev/tg-next: commands to explore dependencies
Two new commands to explore the dependencies of TopGit branches:
a) tg prev [-i | -w] [NAME]
outputs the dependencies of NAME b) tg next [-i | -w] [NAME]
outputs branches which depends on NAMEObviously, quilt next was the inspiration.
