1.6 Unimplemented Features
Unimplemented features include:
- :ab and :una are not implemented,
since :ab is considered obsolete, since Emacs has
much more powerful facilities for defining abbreviations.
- :set option? is not implemented. The current
:set can also be used to set Emacs variables.
- :se list requires modification of the display
code for Emacs, so it is not implemented. A useful alternative
is
cat -t -e file. Unfortunately, it cannot be
used directly inside Emacs, since Emacs will obdurately change
‘^I’ back to
normal tabs.
