Work around a autosetup --help bug which only(?) triggers on tcl 8.6, introduced by [9978c87139b7b042] and reported upstream as [https://github.com/msteveb/autosetup/issues/73|ticket #73]. Summary: calling 'options' from a proc, instead of the global scope, triggers an error about an invalid use of 'break'. (tags: trunk)
