The source cache option takes the same values as the cache option. The
documentation reads a little strange because it starts with "In contrast
the src_cache option ...". The fact that this is comparing with the
previous documented option (the 'cache' option) is implicit. Readers
may be confused, especially if they jump to src_cache without reading
cache documentation first.
