[BUG] BNF does not match the implementation about node-semver

[mbtools]

Because it was invented 10 years ago. I'm working on a update to a formal EBNF that will settle several issues (PR after my vacation)

Agree. Numeric parts of a pre-release must not have leading zero. Also the part definition isn't BNF but a regex.

How about this?

alphanum   ::= ( ['0'-'9'] | ['A'-'Z'] | ['a'-'z'] | '-' ) +
pre        ::= ( nr | alphanum ) ( '.' ( nr | alphanum ) ) *
build      ::= alphanum ( '.' alphanum ) *

PS: This isn't perfect since alphanum could be a just numbers starting with a zero but the definition makes the difference between pre-release and build much clearer.

Sorry for the late response. I was on Chinese Spring Festival.

It looks good to me!

And just out of curious, why we did not keep it same with(or close to) Semver?
