Jim Warner 7060f9ab3a top: circumvent an ncurses version 5.9.20121017 glitch
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)

COMPATIBILITY

    This code is intended for use with Linux 2.6.xx, 3.x and
    hopefully all future kernels.

INSTALLATION

    If you are using git version of the project you need extra step.

    ./autogen.sh

    After that, and everyone using .tar.xz version of procps-ng, can
    do normal build.  Read './configure --help' to select options for
    your needs.

    ./configure
    make
    make install

    If you have DejaGNU installed you can run optional test suite.

    make check

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.
