The following patches modify CED to default to insert (instead of
overtype) mode for each line, and to not reset the mode when
moving up or down the stack, which is more like typical text
editors. Note that the mode toggling function of the <Ins> key
is not affected, but that the block cursor now signifies overtype
(instead of insert) mode.
The first patch bypasses the automatic mode reset that
normally occurs whenever the up or down arrow keys are
pressed, leaving the mode unchanged instead.
The second patch reverses the mode byte (4CC) logic, so that
zero means insert mode and non-zero means overtype mode.
Of course, before the patches are applied the program should be
backed up! (Either DEBUG or SYMDEB may be used.)
