And I don't understand your posting.
"Don't hold your breath waiting for this to be fixed" is an expression that means that what you are expecting is not likely to happen any time soon.
The existing LiquidCrystal library is far from perfect but it is a lot better than the one it replaced several years ago. When the new version was introduced I pointed out some of its remaining problems to both the author (Lady Ada of Adafruit) and to the Arduino people by means of the earlier forum. As you can see nothing has been corrected.
I hope that your efforts to have the library improved are successful but I don't think that will happen anytime soon. You might want to look into this replacement library --> https://bitbucket.org/fmalpartida/new-liquidcrystal/wiki/Home.
