delete_text

Deletes a sequence of characters from the buffer.

n_chars characters are deleted starting at position. If n_chars is negative, then all characters until the end of the text are deleted.

If position or n_chars are out of bounds, then they are coerced to sane values.

Note that the positions are specified in characters, not bytes.

Parameters:

this	a EntryBuffer
position	position at which to delete text
n_chars	number of characters to delete

Returns:

The number of characters deleted.
