Subject: [PATCH] zsh completion: ignore multi-line output in Flags
PR #4475 introduced an interesting twist on --help: a help
string that spans multiple lines. This broke zsh completion.
I'm not keen on that multi-line output, but it shouldn't
break completion. Fix is simple: look only for flag lines
beginning with '-', filter out anything else.
Fixes: #4738
