Using strapply in gsubfn we can match by contents rather than
delimiter. Parentheses in the regular expression
surround captured portions. The first such captured portion is
any string not containing a dot. We then follow that by matching
a dot and a second captured expression which is anything.
c just concatenates the captured strings into a vector of strings.
