Description extraction bugs (tracking)

[iamkaran]

This is a long living issue as its tracking the extraction bugs.

Flag	Issue	Reason	Fix
mpv --fs	finds false positives from man page	help output has the actual description	indent check maybe?
git pull --rebase	outputs "true..."	desc starts in second line and first line has "true"	length check?
go build -o	description not found	it lives in go help build not go --help	as a fallback, use help as a sub command
tmux new-session	sub command isnt found	whats combines to man tmux-new-session but man tmux has it instead	parse sub commands in man cmd as well
