Log Message:
Update gettext* to 0.19.6:

Version 0.19.6 - September 2015

* Programming languages support:
  - AppData:
    xgettext now supports AppData file format, used by software center
    applications (e.g., GNOME Software) to describe installable
    applications.

* A new macro AM_GNU_GETTEXT_REQUIRE_VERSION can be used to indicate
  autopoint to pull the latest available infrastructure, instead of
  the exact version specified with AM_GNU_GETTEXT_VERSION.  When
  AM_GNU_GETTEXT_REQUIRE_VERSION is used, AM_GNU_GETTEXT_VERSION is
  ignored.

* po/Makefile.in.in can now insert the file $(DOMAIN).pot-header to
  $(DOMAIN).pot, instead of the standard header comments.

* Bug fixes:
  - Fix mishandling of gettext version numbers for minor releases, in
    po-mode.el and gettextize.
  - Fix build with --enable-relocatable.

Version 0.19.5 - July 2015

* xgettext now has a feature to perform syntax checks on msgid, which
  could enforce common styles of translatable strings, such as to
  prefer Unicode characters to the corresponding ASCII characters.
  They can be enabled with --check option or special "xgettext: "
  comment in the source code.  By default, no syntax checks are
  enabled.

* msgfilter and msgexec now have an option --newline, which appends a
  newline character to filter input and trims it from the filter
  output.  This would allow filter programs to be more POSIX friendly.

* The base Unicode standard is now updated to 8.0.0.  This
  particularly improves "\N{...}" notation handling of xgettext for
  Perl and Python.

* msginit is now capable of generating "Plural-Forms:" from Unicode
  CLDR.  This feature is still experimental, but you can try it by
  setting the GETTEXTCLDRDIR environment variable pointing to the
  directory where the CLDR archive is extracted.  The actual
  conversion is done by a helper program 'cldr-plural', which can be
  used as a generic converter and evaluator of CLDR plural forms.

* Programming languages support:
  - C++ with KDE: xgettext and msgfmt can now recognize KUIT (KDE User
    Interface Text) markup.  See the documentation section "KUIT
    Format Strings" for more info.
  - C++ with KDE: xgettext now recognizes all default KDE keywords.
    This removes the need for a long list of --keyword and --flag
    options to perform a reasonable extraction.

* Bug fixes:
  - xgettext C++11 raw string recognition is now stricter and don't
    accept unbalanced delimiters.
  - Suppress baseless warnings which msgfmt emits when processing a
    .desktop file.
  - xgettext line wrapping behaviour is now consistent between comment
    lines and non-comment lines.
  - Fix msgfilter-7 test failure on some platforms.
  - Fix VPATH build.
