When a string is used as a separator, the behaviour isn't entirely
obvious. If the string is passed as the separator argument to
G_tokenize(), it treats the string as a set of characters, all of
which are treated as separators.
For a module to provide this behaviour, it would be more natural to
use e.g. "opt.sep->multiple = YES" and require the individual values
to be single characters (after any parsing of backslash sequences).
