No top #define is enabled and that constitutes default
behavior. So whenever a default behavior should change
the define must be changed too if it is to remain off.
This commit simply changes top's default behavior with
respect to allowing/suppressing any potential flood of
SIGWINCH during resize operations, if running under X.
Formerly top would block those signals to reduce costs
of repeated refreshes. That yields a requirement where
the user would have to provide another keystroke for a
final display update. That keystroke may not always be
needed now, but it ultimately depends on some terminal
emulator's scrollback buffer. In any case, the cost of
re-sizing may go up a bit, under most window managers.
(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)

HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
