* generic/tkInt.h: moved new TkDisplay useInputMethods structure
element to end to not disturb position of previous elements in
the structure (as compared to Tk <=8.2).
* generic/tkCanvLine.c (LineCoords): fixed segfault when too few
coords were passed to a line with certain options set (it should
always have thrown an error anyway). [Bug: 4042]
* tests/text.test:
* generic/tkText.c: fixed missing " in error case and missing
'dump' in subcommand listing [Bug: 4036]
* generic/tkListbox.c: adjusted use of basic string concatenation
in (non-K&R behavior) [Bug: 4027]
Swapped bg/fg class for -select(bg|fg) for listbox and their
items [Bug: 4039]
