* This is necessary to fix the Unicode test suite on Win32,
  so I was always passing in --disable-shared manually.
  It's easy to forget though when building from scratch.
* We don't currently install any (shared) library, so this is safe
  on all platforms.
  In fact on all other platforms, libtool detects that and doesn't
  generate wrapper binaries in any way.
  Only on win32 it's apparently buggy.

* character-based model, avoid mentioning "ASCII code"
* added "0EE" example
* should be built with pdfmom, so it's built with gropdf

* This pushes to the gh-pages branch since we don't yet want to introduce a new
  workflow (that would have to rebuild SciTECO).
* Built as part of the nightly MacOS builds.
  The Ubuntu builds directly build Debian packages which do not contain the
  HTML manuals.
* I don't want to check in images into the master branch.
  The gh-pages branch is cleaned with every build.
  Therefore I still cross-link to Sourceforge for any additional images
  and documents.
* We could automatically build the cheat-sheet.pdf (TODO?).
  For the time being, we are still linking to Sourceforge.

* The libtool wrapper binaries do not pass down UTF-8 strings correctly,
  so the Unicode tests failed under some circumstances.
* As we aren't actually linking against any locally-built shared libraries,
  we are passing --disable-shared to libtool which inhibts wrapper generation
  on win32 and fixes the test suite.
* Also use up to date autotools. This didn't fix anything, though.
* test suite: try writing an Unicode filename as well
  * There have been problems doing that on Win32 where UTF-8 was not
    correctly passed down from the command line and some Windows API
    calls were only working with ANSI filenames etc.

The Mac OS 12 Groff apparently does not accept `-K` for preconv.

Should fix `make distcheck`.

* `make distcheck` will try to build against libncurses, which is not installed.
  Therefore, I set DISTCHECK_CONFIGURE_FLAGS in order to force it to PDCurses.

* You no longer have to copy contrib/scintilla, contrib/scinterm and contrib/lexilla
  manually to the build directory.
* It turns out, that Scintilla/Lexilla was supporting this since 2016.
  Scintilla allows pointing to a source directory (srdir) and Lexilla to a binary directory (DIR_O).
* For Scinterm I opened a pull request in order to add srcdir/basedir variables:
  https://github.com/orbitalquark/scinterm/pull/21
* `make distcheck` is therefore now also fixed.
* The FreeBSD package is now allowed to build out of source.
  I haven't tested it yet.
