git lab allow branching from trunk only. It's not convenient to force the branching with --current when actually being on main or master branches.

I guess we would like to allow a small list of trunk like branches. Such a list could be:

• trunk
• main
• master

- if ( $current_branch eq 'trunk' && !$opt_for->{current} ) { ... }
+ if ( $current_branch !~ /^(main|master|trunk)$/ && !$opt_for->{current} ) { ... }

Configuration file could also provide additional custom branch names.
