Add a new option, -W, to show the whole surrounding function of a match. It uses the same regular expressions as -p and diff to find the beginning of sections. Currently it will not display comments in front of a function, but those that are following one. Despite this shortcoming it is already useful, e.g. to simply see a more complete applicable context or to extract whole functions.
