Readme documentation gives invalid PHC string as example?

[dkushner]

Phrased as a question as I am potentially just misreading the spec, but in the README I see reference to this string as a valid output of the bcrypt call:

$bcrypt$v=98$r=10$Fu+++1sHIGTodjyG4pF4Sw$QlOihTVOARhpV0EiWv4k10i5Pw5Hm0E

Would this not be invalid according to the PHC string format specifications? According to this document, the expected layout of a string is:

$<id>[$<param>=<value>(,<param>=<value>)*][$<salt>[$<hash>]]

Meaning the example would be interpreted as:

function => bcrypt
parameters => { v => 98 }
salt => r=10
hash => Fu+++1sHIGTodjyG4pF4Sw$QlOihTVOARhpV0EiWv4k10i5Pw5Hm0E

The salt here would be invalid since the base64 encoding prescribed by the standard excludes the use of the equal character as padding, but I think this is more a mistake of using the $ separator for a parameters list rather than a comma.
