New description:
A language pragma like
{{{
{-# LANGUAGE
TypeOperators,
FlexibleContexts #-}
}}}
parses just fine but
{{{
{-# LANGUAGE
TypeOperators,
FlexibleContexts
#-}
}}}
doesn't, saying:
{{{
Cannot parse LANGUAGE pragma
Expecting comma-separated list of language options,
each starting with a capital letter
}}}
An OPTIONS pragma, on the other hand, accepts either format without
complaint.
