Detailed Description
A datastructure holding a line of text in an edit session. Lines of text are tab expanded before display and binary characters are converted into ~'s for display purposes.
If you don't change a line of text, the tab expansion never gets written back to the file, even if you save the edit session, but if you do save, any changed lines will be tab packed before writing.
This data structure keeps two pointers -- one pointer if the data is never modified and the other if it is. It could be done with a flag and a pointer, but it would take up the same space on most machines.
