Add formatting to handle binary literals, which were added in Scala 3.5.0.
Those are of the form 0b111 or 0b111L and so are susceptible to both literals.binPrefix and literals.long.
The 3.5.0 release uses 0B111 in its examples, but the original SIP 42 uses 0b111. I chose 0b as the default, as it looks a lot nicer to me.
There is a new test file (
binary.stat
) and the documentation was updated (it's missing asince
comment).The changes address my own feature request: fixes #4176.
