use GRAMMAR & argparse or bruteforce?
doing brute force, still stuck in parser mindset tho
add add, branch-create
add branch rename
branch delete
listmode
fix bugs
help outside switch-case
Merge branch 'master' into parse_jgit
remove +++ for H3
move code to parsebranch function, always use case-sensitive str comparison
send cell array of filepatterns to add if more than one
use filterOpts to find double-hyphen
start work on checkout
checkout new branch
add pop arg, to keep or loose dbl hyp
fix strcmp needs any bug in checkout, change error msgid to parse*
remove most commonly used git commands from help, just show release once, but copyright everywhere
be consistent no >> for any code snippets
move parseCMD, filterOpts to private/

* new style help in private/jgit_help shows synopsis consistent with man
 pages, but only available jgit commands.
* show version and call update to download latest jar
* show available commands for jgit help
