I agree. IMHO options should be presented like a list of checkboxes in a
dedicated temporary buffer. In addition to multiple selections,
advantages include:

* no mabiguity if several options have same value and/or text
* can handle option with empty text
* can handle disabled options
* present options in the order intended, not alphabetized as in minibuffer 
completions
* search commands are available (userful if there are many options)

Couldn't a large part of the code for checkboxes/radio buttons be reused?
