add a parameter to makeTokenParser to specify options for treating space by lexeme

[ciez]

Sometimes space around tokens matters a lot. Take Haskell dot for example.

This proposal is to add a parameter to makeTokenParser

parsec/src/Text/Parsec/Token.hs

Lines 358 to 361 in 38dfc54

	makeTokenParser :: (Stream s m Char)
	=> GenLanguageDef s u m -> GenTokenParser s u m
	{-# INLINABLE makeTokenParser #-}
	makeTokenParser languageDef

which would explicitly specify lexeme options:

• consume trailing space
• do not consume trailing space
