New-style spec-version
1 declarationQuickly scan new-style spec-version
A new-style spec-version declaration begins the .cabal file and follow the following case-insensitive grammar (expressed in RFC5234 ABNF):
newstyle-spec-version-decl = "cabal-version" *WS ":" *WS newstyle-spec-version *WS
spec-version = NUM "." NUM [ "." NUM ]
NUM = DIGIT0 / DIGITP 1*DIGIT0
DIGIT0 = %x30-39
DIGITP = %x31-39
