 Currently the {{{get_the_content()}}} and {{{get_the_excerpt()}}}
 functions return the values from the loop but do not allow a Post object
 to be passed.  These functions in the patch ({{{get_post_content()}}} and
 {{{get_post_excerpt()}}}) save and then restore the global variables
 assigned by {{{setup_postdata()}}} so that {{{get_the_content()}}} can be
 called for a specific post.

 The functions to save and restore the postdata are {{{save_postdata()}}}
 and {{{restore_postdata()}}} respectively, and they simply capture the
 values of the global variables set in {{{setup_postdata()}}} into an array
 and then restore them back from the array.

 This is the first of a broader patch I hope to supply with functions for
 {{{get_post_*()}}} and {{{the_post_*()}}} that would each receive as their
 first parameter a Post object/post ID/post array and as a second an array
 of {{{$args}}} so that robust code can be written related to posts and so
 that there will be a set of functions for this with a ''consistent'' set
 of parameters.
