Here's an analogy: (string-match "xyzzy" "fooxyzzybar") returns 3.
This is because the first 5 characters starting at position 3 are
"xyzzy", the same as the first string parameter.  The significance of
5 here is the length of "xyzzy".

Similarly, (string-match "" "foo") returns 0.  This is because the
first 0 characters starting at position are "", the same as the first
string parameter.
