devel/git-branchless 0.11.1_4 FreeBSD

`git-branchless` is a suite of tools which enhances Git in several ways: It makes Git easier to use, both for novices and for power users. Examples:

• `git undo`: a general-purpose undo command.
• The smartlog: a convenient visualization tool.
• `git restack`: to repair broken commit graphs.
• Speculative merges: to avoid being caught off-guard by merge conflicts.

It adds more flexibility for power users. Examples:

• Patch-stack workflows: strong support for "patch-stack" workflows as used by the Linux and Git projects, as well as at many large tech companies. (This is how Git was "meant" to be used.)
• Prototyping and experimenting workflows: strong support for prototyping and experimental work via "divergent" development.
• `git sync`: to rebase all local commit stacks and branches without having to check them out first.
• `git move`: The ability to move subtrees rather than "sticks" while cleaning up old branches, not touching the working copy, etc.
• Anonymous branching: reduces the overhead of branching for experimental work.
• In-memory operations: to modify the commit graph without having to check out the commits in question.
• `git next/prev`: to quickly jump between commits and branches in a commit stack.
• `git co -i/--interactive`: to interactively select a commit to check out.
