* the registers beginning with "$" are exported into sub-process
environments. Therefore macros can now modify the environment
(variables) of commands executed via EC/EG.
A variable can be modified temporarily, e.g.:
[[$FOO] ^U[$FOO]bar$ EC...$ ][$FOO]
* SciTECO accesses the global environment registers instead of
using g_getenv(). Therefore now, tilde-expansion will always
use the current value of the "$HOME" register.
Previously, both register and environment variable could diverge.
* This effectively fully maps the process environment to a subset of
Q-Registers beginning with "$".
* This hasn't been implemented by mapping those registers to
special implementations that updates the process environment
directly, since g_setenv() is non-thread-safe on UNIX
and we're expected to have threads soon - at least in the GTK+ UI.

working directory
* FG stands for "Folder Go"
* FG behaves similar to a Unix shell `cd`.
Without arguments, it changes to the $HOME directory.
* The $HOME directory was previously only used by $SCITECOCONFIG on Unix.
Now it is documented on its own, since the HOME directory should also
be configurable on Windows - e.g. to adapt SciTECO to a MinGW or Cygwin
installation.
HOME is initialized just like the other environment variables.
This also means that now, the $HOME Q-Register is always defined
and can be used by platform-agnostic macros.
* FG uses a new kind of tab-completion: for directories only.
It would be annoying to complete the FG command after every
directory, so this tab-completion does not close the command
automatically. Theoretically, it would be possible to close
the command after completing a directory with no subdirectories,
but this is not supported currently.
* Filename arguments are no longer completed with " " if {} escaping
is in place as this brings no benefit. Instead no completion character
is inserted for this escape mode.
* "$" was mapped to the current directory to support an elegant way to
insert/get the current directory.
Also this allows the idiom "[$ FG...new_dir...$ ]$" for changing
the current directory temporarily.
* The Q-Register stack was extended to support restoring the string
part of special Q-Registers (that overwrite the default functionality)
when using the "[$" and "]$" commands.
* fixed minor typos (american spelling)

* this makes them absolute and also resolves links on Unix
* macros can now assume the corresponding Q-regs to be absolute
* Currently this does not make a big difference since the
working directory of the SciTECO process cannot be changed.
Once I implement a command to change the working dir, this
is essential.

* The PACKAGE_URL_DEV is also mentioned in --help output and sciteco(1)

* It is no longer possible to accidentally open save point files
of the same or another SciTECO instance when typing something like
EB*.cpp$
* The use of a trailing ~ is common among editors. These files
will be recognized more easily as temporary by users.
* People will often already have VCS ignore rules for files with
trailing tilde. Therefore SciTECO savepoints will often be
already ignored by VCS.
* Since they still have a unique ".teco" prefix, they will not
be confused by other programs as backup files.
* Also mention in sciteco(1) that save point files are hidden on
Windows.

* session.hg sets up the buffer session in the current
Mercurial repository
* session.vcs is a convenience macro that may be used in
profiles to enable buffer sessions per repo for all supported
VCS (Git, Hg and SVN)

$SCITECOPATH on Windows
* $SCITECOCONFIG has been introduced, so have a macro-accessible location
for the profile, buffer session etc.
This is set to the program dir on Windows. That way, the config files
will be found, regardless of the current working dir, but it may also
be set up for Unix-like environments on Windows.
* $SCITECOPATH defaults to the program dir + "/lib" now on Windows.
* The default profile is now always called ".teco_ini". Also on Windows.
Platform differences like this would need to be documented.
* The sample teco.ini has been renamed to "sample.teco_ini" for clarity

this will allow us to use the same algorithms for loading and saving
Q-Registers (from/to file).
* Saving with EW when a Q-Reg is edited has been fixed (was broken earlier)
* SciTECO save point files are now named .teco-X-BASENAME
When using IOView for Q-Regs, there will be no way to sensible count
the save points. Each write of a Q-Reg may be to another file.
Therefore, we number save-points globally.
If the sequence of writes has to be reconstructed manually,
one can still look at the save point files' modification dates
* give more informative error messages when saving a file fails

useful for Windows where the desired default path does not correspond with
the installation dir of the std lib macros
|
|
* SCITECOPATH environment variable defaults to this directory
* manpage updated
* default teco.ini updated: no need to generate it anymore

later there will be much more documentation
