goodbye END-CHOOSE

Browse Source 
Instead of an additional options file directive to end the last
section of a CHOOSE directive, simplify by using an empty-name
section, [], instead.  So
...
CHOOSE one,two
[one]
...
[two]
...
[]
...

As with the short-lived END-CHOOSE directive, if no [] is present
then the rest of the file is part of the last choice.

An optional way to terminate CHOOSE.
You can place an END-CHOOSE directive after the last CHOOSE section in
order to follow that with other options which are common to all sections.

If {\tt []} is present, the preceding section is closed and no new
section begins; whatever follows will be common to all sections.
Otherwise the last section extends to the end of the options file.
