321b781e29 refresh values of “Portability” field
‘Text.Megaparsec.Prim’ cannot be considered portable since it uses
multi-parameter type classes and functional dependencies.

Other modules that depend on these non-portable features from
‘Text.Megaparsec.Prim’ should be considered non-portable too.

6627690363 fixed a typo in test for ‘updatePosString’
That typo was causing loop. Also, since we don't treat carriage return
specially, we can simplify the test a bit.

3975ae52d0 cosmetic improvements, courtesy of @neongreen
Closes #37.

Most part of these changes is proposed by @neongreen. To apply precisely
what I deem acceptable, correct some of them in other way, and add some
other things, I've manually re-edited this.

d0409a897e implemented flexible tab width
Closes #38.

Now tab width can be manipulated with via the following functions:

* ‘getTabWidth’
* ‘setTabWidth’

Other auxiliary changes were performed, such as updating of
‘updatePosChar’.

This also corrects a bit obsolete descriptions of some functions.

38abf590db make ‘string'’ return actually parsed input
Closes #36.

We should try to preserve original information where possible. User then
can convert case of parsed string if necessary. Previous implementation
discarded actually parsed string and returned argument of the
function — this can be considered as data loss of a sort.

dcc53ad0b7 improved error messages for labelled ‘many’
Closes #35.

Since ‘many’ (and thus ‘some’) are the only combinator that can succeed
consuming input and produce hints at the same time we can conclude that
‘cok'’ continuation in ‘pLabel’ combinator is only called when ‘many’ is
labelled. By correcting label in this case prepending the phrase “rest
of ” to actual label we can greatly improve result error message.

fce6c3187c eliminated user state and written ‘MonadParsec’
Close # 27.

Backtracking user state can be achieved via combination of ‘StateT’
monad transformer and ‘ParsecT’:

  StateT StateType (ParsecT s m a)

This user state can be more flexible. This fact renders current built-in
user state redundant.

To help work with this new approach (combining monad transformers more
freely) we introduce ‘MonadParsec’ MTL-style type class. All tools that
come with Megaparsec library were modified to work smoothly with any
instance of ‘MonadParsec’, not only ‘ParsecT’.

Closes #29.

Now testing function can return ‘Either [Message] a’ so it can construct
full list of error messages. This may be useful in some cases when
tokens are more complex than simple characters.
