doc: Keep copyright and license comments from showing up in TeX output.
The "\input texinfo" line is what changes the comment syntax from TeX
syntax to Texinfo syntax, so it has to go before the @c comments or else
those comments show up in output produced by TeX.

perl-module: Avoid VERSION redefinition warning from compiler.
If the PSPP version includes a suffix like "-pre1", then Perl will strip
that suffix from the version it passes to the compiler using -DVERSION=...,
and <config.h> will re-define it with the full version string. This causes
a warning.
This change avoids the warning. I am not yet aware of a new problem that
it causes.
Fixed perl regression problem due to Version name - Fixes Bug #51218
The regression failed in some perl tests due to an incompatible
pspp version number. I changed to a version number that includes
a "-". The problem is described in acinclude.m4. See
The PSPP autobuilder appends a build number to the PSPP version number,
e.g. "0.7.2-build40". But Perl won't parse version numbers that contain
anything other than digits and periods, so "-build" causes an error. So we
define $(VERSION_FOR_PERL) that drops everything from the hyphen onward.
VERSION_FOR_PERL=`echo "$VERSION" | sed 's/-.*//'`
AC_SUBST([VERSION_FOR_PERL])
The version name was 0.10.5pre1 without a "-". Therefore the version name
for perl results in a problem.

FACTOR: Use consistent indexing when displaying matrices.
In any sane use case this will make no difference, since
all covariance and correlation matrices are symetrical.
However for correctness and ease of debugging this helps.

Terminal interface: Remove support for the ncurses library.
This library was supported for trivial reasons. It always gave rise
to portability issues and was a pain to support. Furthermore there
is a simpler way to do what we used it for. So now we use that way
instead.

Fixed a bug in the Mann-Whitney test vs. missing=analysis.
When missing values were deleted from the dataset, they were deleted after the
ranks for the U value had been inserted, - thus the wrong rank sum would be
calculated. This change deletes missing values *before* the ranks are inserted.
