-## usage: findstr (s, t [, overlap])
-##
-## Returns the vector of all positions in the longer of the two strings
-## S and T where an occurence of the shorter of the two starts.
-##
-## If the optional argument OVERLAP is nonzero, the returned vector
-## can include overlapping positions (this is the default).
-##
-## For example,
-##
-##   findstr ("abababa", "aba")     =>  [1, 3, 5]
-##   findstr ("abababa", "aba", 0)  =>  [1, 5]
