 This patch adds two features to get_posts(), while maintain backward
 compatibility with all previous invocations:

  * The category variable may be a comma-separated list, specifying
 selection of posts from multiple categories.
 {{{
 #!php
 get_posts('numberposts=5&category=1,5,6'); // get the 5 most recent posts
 from categories 1,5, and 6 (singular still works as before)
 }}}
  * The query may be inverted, so that the results are from any categories
 BUT the ones specified.
 {{{
 #!php
 get_posts('numberposts=5&category=3,4&category_exclude=1'); // get the 5
 most recent posts from all categories other than categories 3 and 4
 (singular also works)
 }}}

 I haven't thoroughly tested this code, it's more for discussion purposes
 at this point. But I'm fairly confident that it's a complete solution.

 (btw-- there is no 2.2.3 yet in the trac version menu)
