Some testing under a new distro revealed what appeared to be a broken top Inspect request. When the selection was made, the resulting output was scrambled/scrunched at the bottom of the screen (as if ^J's were missing). This anomaly surfaced under Fedora-18 which happens to use the above ncurses version. The bug was not present in version 5.9.20120714 (available with openSUSE 12.2) or the more widely available version of: 5.9.20110404. It has now been confirmed that this problem originated in version 5.9.20120825. It was then that buffering of output was changed from stdio to some internal ncurses scheme so as to avoid problems with its SIGTSTP logic. Thanks to a very prompt response from Thomas E. Dickey we also learned that contrary to the documentation the putp logic does not call putchar internally. Thus, the single putchar that Inspect was employing was actually mixing 2 different buffering schemes: ncurses & stdio. Thus, from now on we'll use putp() exclusively and try to achieve single char output as efficiently as we can while meeting that putp() string argument requirement. (everything is perfectly justified plus right margins) (are completely filled, but of course it must be luck) Reference(s): https://bugzilla.redhat.com/892674 Signed-off-by: Jim Warner <james.warner@comcast.net>

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.
