@delete
Description:
Deletes text between start and end.
The order of start and end is not actually relevant; @delete will reorder them. This
function actually emits the “delete-range” signal, and the default handler of that signal deletes the text. Because the buffer is modified,
all outstanding iterators become invalid after calling this function; however, the start and end will be
re-initialized to point to the location where text was deleted.
Parameters:
| this | |
| start |
a position in this |
| end |
another position in this |
