stack: introduce and explicite command to display the stack
If is worth testing having the feature lives outside 'hg topic --list'. The
'stack' name is sub optimal because the conflict with 'status'. using "hg st"
would still work as 'st' is hard coded, but this mean 'hg stack' has no short
version.
# topics
Topics are an experiment to see if maybe the workflow defined by git
branches and hg bookmarks is only partially what users want - perhaps
something that feels more like a traditional VCS branch is right, but
that it should "dissolve" upon being finished. This extension exists
to be a sandbox for that experimentation.
# usage
Enable topics like any mercurial extension: download the source code to a
local directory, and add that directory to your `.hgrc`:
[extensions]
topics=path/to/hg-topics/hgext3rd/topic/
