* mapped to different registers beginning with "~"
* on supported platforms accessing the clipboard is as easy as
X~ or G~.
Naturally this also allows clipboards to be pasted in
string arguments/insertions (^EQ~).
* Currently, Gtk+, PDCurses and ncurses/XTerm are supported.
For XTerm clipboard support, users must set 0,256ED to enable
it since we cannot check for XTerm window ops programmatically
(at least without libX11).
* When clipboard regs exist, the clipboard can also be deemed functional.
This allows macros to fall back to xclip(1) if necessary.
* EOL handling has been moved into a new file eol.c and eol.h.
EOL translation no longer depends on GIOChannels but can be
memory-backed as well.

* added a new OPTIONAL behaviour for QRegSpecMachines
* allows you to implement commands that have an optional Q-Register
argument that should not be initialized if undefined.
* Using QRegSpecMachine::fail() you may still check for existence of
the register conditionally to emulate the QREG_REQUIRED behaviour.
* Using :Q for checking for register existence makes sense, because
usually you will want to check for both existence and non-emptyness
as in :Qq">. So in this common case, you no longer have to
keep in mind that the register may also be undefined.
* This finally allows us to create arrays in the Q-Register
tables without keeping a separate entry for the number of elements.
E.g. an array.0 to array.N can be iterated like this:
0Ui <:Q[array.^E\i]:; ! work with element i ! %i>

* this means that QRegSpecMachine::input() no longer has to return
a dummy QRegister in parse-only mode.
This saves an unnecessary QRegister table lookup and speeds up
parsing.
* QRegSpecMachine can now be easily extended to behave differently
when returning a Q-Register, e.g. simply returning NULL if a register
does not exist, or returning a register by prefix.
This is important for some planned commands.
* StateExpectQReg::got_register() now gets a QRegister *.
It can theoretically be NULL - still we don't have to check
for NULL in most cases since NULL is only passed in parse-only mode.

* activated via bit 4 of the ED flag (enabled by default)
* automatic EOL guessing on file loading and translation to LFs.
* works with files that have inconsistent EOL sequences.
* automatic translation to original EOL sequences on file saving
* works with inconsistent EOL sequences in the buffer.
This should usually not happen if the file was read in with
automatic EOL translation enabled.
* also works with the EC and EG commands
* performance is OK, depending on the file being translated.
When reading files with UNIX EOLs, the overhead is minimal
typically-sized files. For DOS EOLs the overhead is larger
but still acceptable.
* Return (line feed) is now an immediate editing command.
This centralizes EOL sequence insertion.
Later, other features like auto-indent could be added to
the editing command.
* get_eol() has been moved to main.cpp (now called
get_eol_seq()
* Warn if file ownership could not be preserved when
saving files.
* IOView has been almost completely rewritten based
on GIOChannels. The EOL translation code is also in IOView.

* the GError expection has been renamed to GlibError, to avoid
nameclashes when working from the SciTECO namespace

normally, since SciTECO is not a library, this is not strictly
necessary since every library should use proper name prefixes
or namespaces for all global declarations to avoid name clashes.
However
* you cannot always rely on that
* Scintilla does violate the practice of using prefixes or namespaces.
The public APIs are OK, but it does define global functions/methods,
e.g. for "Document" that clashed with SciTECO's "TECODocument" class at
link-time.
Scintilla can put its definitions in a namespace, but this feature
cannot be easily enabled without patching Scintilla.
* a "SciTECO" namespace will be necessary if "SciTECO" is ever to be
turned into a library. Even if this library will have only a C-linkage
API, it must ensure it doesn't clutter the global namespace.
So the old "TECODocument" class was renamed back to "Document"
(SciTECO::Document).

powerful command for filtering a SciTECO buffer through an external
program. It will be described in the sciteco(7) man pages.
The implementation uses an asynchronous background process with
pipes but is platform independant thanks to glib's g_spawn functions,
GIOChannels and event loops.
There are however platform differences in how the operating system
command is interpreted/parsed.
