/** A searchable character on the document canvas.
*
* struct document.search is an array of struct search, initialised by
* get_src, q.v. The elements of the array roughly correspond to the document
* canvas, document.data; each element corresponds to a regular character, a
* run of one or more control characters, or the end of a line on the canvas.
*
* If an instance of struct search corresponds to a regular character, then that
* character is stored in @a c and @a n is equal to 1. If an instance of struct
* search corresponds to a run of control characters, then a space character ' '
* is stored in @a c and @a n is equal to to the length of the run. If an instance
* of struct search corresponds to the end of a line, then a space is stored in
* @a c and @a n is equal to 0.
