* It requires a forced refresh on startup (even though that should be the
  default). Otherwise, it wouldn't print the info line correctly.
* Redirect stdin and pass it to newterm() to fix key queuing.
  Probably necessary for supporting ncurses on NetBSD as well.
* Avoid doupdate() if screen is too small: fixes crashes for very
  small windows.
* Updated Scintilla: There were some implicit typing assumptions,
  that are broken by this platform.

Esp. mention the new OBS repositories.

* Since OBS has its own VCS, there is no need to add the sciteco.spec
  to this repository.
  It's located here:
  https://build.opensuse.org/projects/home:rhaberkorn:sciteco:STABLE/packages/sciteco/files/sciteco.spec
* We will probably provide nightly builds via the UNSTABLE subproject as well.
* Perhaps OBS will even be used to build Debian packages,
  as PPA only works on Ubuntu.
  Also it has a webinterface for downloading the binary packages, so these
  could be removed from our nightly CI workflows.

* In principle --stdin and --stdout could have been done in pure TECO code using the
  <^T> command.
  Having built-in command-line arguments however has several advantages:
  * Significantly faster than reading byte-wise with ^T.
  * Performs EOL normalization unless specifying --8bit of course.
  * Significantly shortens command-lines.
    `sciteco -qio` and `sciteco -qi` can be real replacements for sed and awk.
* You can even place SciTECO into the middle of a pipeline while editing
  interactively:
  foo | sciteco -qio --no-profile | bar
  Unfortunately, this will not currently work when munging the profile
  as command-line parameters are also transmitted via the unnamed buffer.
  This should be changed to use special Q-registers (FIXME).
* --quiet can help to improve the test suite (TODO).
  Should probably be the default in TE_CHECK().
* --stdin and --stdout allow to simplify many SciTECO scripts, avoiding
  temporary files, especially for womenpage generation (TODO).
* For processing potentially infinite streams, you will still have to
  read using ^T.

Also updated NEWS: mention v2.4.0 release.

* `--enable-html-manual` renamed to `--enable-html-docs`.
* It's also uploaded to the website and linked to in README.

* Added a test case for the known bug of out-of-place modifiers.
  Well, this is a syntactic shortcoming rather than a true bug.
  But I did run into it more than once.

This will at least show the currently packaged versions on the website.
