updated ffx -- file dialog

["Klaus Schmid" <klaus.schmid@xxxxxx>]

Hi all,

the updated ffx.sl is almost completly redesigned.
http://home.wtal.de/klaus/jedks/

The idea is to create/use one file dialog function for all
applications as find_file, write_buffer, etc..
The last version tried to tweak the existing functions, this
version provides new ones, more solid imho, since all
the essential functions are in Jed.

The new concept allows cycling up and down with edit keys through
recent files as well through completion files.
This frees the space bar for these pathological MS file names with
embedded spaces. (Sorry for this wording, maybe I see only
the problems and not the benefits of these innovations.)

The recent file list is just above the completion file list. The up/down
arrow
keys at top/bottom allows to switch between both lists.
Additionally the recent file list will pop up directly with page up or page
down.

To make the recent files capable for multi sessions, it seems there is no
other
way to read/write from/on disk at each reference. With a hidden buffer and
Jed's modified-query function some read's could be avoided. To speed up
I used get_doc_string_from_file, but in slow environments it probably gets
annoying or even unusable and this feature has to be turned off.
Any opinion?

Of course I could imagine this combination of Recall/Recent-List and
Completions
could be usable as well for other dialogs like buffer switching and slang
commands.
