* Match command names introduced in v.5.0.0 (August 2024):
"auth", "multiinput", "status", "truecolor".
* Match command names introduced in v.4.5.0 (January 2017):
"defdynamictitle" and "dynamictitle".
* Deprecate command names that have been retired thus far:
"debug", "maxwin", "nethack", "password", "time".
* Remove a spurious "defzombie" command name (this name is
just lamented over in the documentation entry for the
"zombie" command as being more fitting than "zombie"
because its effects are not local to a window; no such
name is entered in "comm.c").
* Separately group the Braille navigation commands, "bd_*",
that may belong to another, superset program Dotscreen:
(see doc/README.DOTSCREEN and commit
848af83f5 elsewhere).
* Revise string escape characters:
- Recognise more characters, "%[`<>=eEfFHOPSxX]".
- Recognise undocumented characters, "%[gNpT]", and list
relevant Screen commits in the comments.
- Match optional qualifiers, "%\%([-+L]\|\d\+\).".
* Match more items in double-quoted command arguments.
* Match unquoted environment variable references.
* Match octal numbers, e.g. "defmode 0622".
* Match escaped octal numbers, e.g. "bind \077 help".
Unless a Dotscreen program (c. 1995) or an older than
v.4.3.1 (c. 2015) Screen program, that was compiled with
"HAVE_BRAILLE" defined, is installed and needs configuring,
add to ".vim/after/syntax/screen.vim":
-----------------------------------------------------------
if hlexists('dotscreenCommands')
syn clear dotscreenCommands
endif
-----------------------------------------------------------
To BACKPORT the updated syntax file to version 4 of Screen,
add to ".vim/after/syntax/screen.vim":
-----------------------------------------------------------
if hlexists('screenDeprecatedCommands')
syn clear screenDeprecatedCommands
endif
if hlexists('screenVersion5Commands')
syn clear screenVersion5Commands
endif
