What I like about the current behavior is that it does not require
additional documentation. The existing documentation is sufficient.
What happens when the first argument is empty is consistent with what
happens when it's not: the first matching substring is replaced, which
in the case of an empty substring means the beginning of the string.
The patch changes a rare case that I don't personally care about, but
it also adds a special case, and I do care about special cases in
general -- I do not like them.
