|
||||
* both of which are significant:
|
||||
*
|
||||
* - If recursed-to lookup is MultipleSubst and buffer length
|
||||
* decreased, then it's current match position that was deleted,
|
||||
* NOT the one after it.
|
||||
*
|
||||
* - If buffer length was decreased by n, it does not necessarily
|
||||
* mean that n match positions where removed, as there might
|
||||
* have been marks and default-ignorables in the sequence. We
|
||||
* should instead drop match positions between current-position
|
||||
* and current-position + n instead.
|
||||
*
|

* It should be possible to construct tests for both of these cases.
