Couldn't we use a fast code path (what we have now) for the case when
the delimiter is a single byte? That would allow for multi-character
delimiters without penalizing those that don't use them.
As for use case, I worked on migrating some stuff out of a MySQL
database a while ago, and having arbitrary string delimiters would have
made life easier.
