A possible suggested rewrite to make it flow a bit better and to
mention the loose whitespace matching:
The xfuncname regex finds functions, structs and interfaces.
Although the Go language prohibits the opening brace of a 'func'
from being on its own line, the regex makes the brace optional so
it can match function declarations wrapped over multiple lines
(covered by new test case t4018/golang-long-func):
func foo(bar int,
baz int) {
}
Whitespace matching is also a bit lax in order to handle
non-standard formatting of method declarations. For instance:
func(x *X) foo() {
versus typical 'gofmt' formatted:
func (x *x) foo() {
(Not necessarily worth a re-roll; perhaps Junio can pick it up when
queueing if he considers it an improvement.)
