[groff] Release Candidate 1.22.4.rc2

[Bertrand Garrigues]

Hi all,

Release candidate 1.22.4.rc2 is now available from GNU's alpha ftp.
Compared to the previous releases (1.22.3.rc1) it includes the latest
2.3 version of 'mom' macro package, new features in 'gropdf' to generate
presentation slides and several fixes.

Notes:

- The previous release was wrongly named 1.22.3.rc1 (it should have be a
  1.22.4.rc1).  All the future RC will have a version and tag
  1.22.4.rcX, and the final 1.22.4 version will be tagged 1.22.4.

- Previously fonts and macro data was installed (by default) in
  /usr/local/share/groff/<full version>.  Now a 'short version' is
  defined that contains only the 3 numbers <major>.<minor>.<patch>, and
  this 'short version' is used as the installation directory instead of
  the full version.  The full version is still used in the various
  scripts and binaries (for example 'groff --version' will return
  'GNU groff version 1.22.4.rc2').

The version can be downloaded here:
https://alpha.gnu.org/gnu/groff/.  To build it and install it:

  mkdir build
  cd build
  ../configure
  make -j <number of core>
  sudo make install

To uninstall it just do 'make uninstall'.  You can also download and
build the 1.22.4.rc2 from git:

  git clone https://git.savannah.gnu.org/git/groff.git
  cd groff
  git checkout 1.22.4.rc2
  ./bootstrap
  mkdir build
  cd build
  ../configure
  make -j
  sudo make install

Thanks to everyone that is willing to test this version.

Regards,

Bertrand Garrigues
