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.
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.
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.
