last-coding-system-specified

[Kenichi Handa <handa@m17n.org>]

I've just noticed this variable:

------------------------------------------------------------
last-coding-system-specified's value is iso-2022-jp

Documentation:
Most recent coding system explicitly specified by the user when asked.
This variable is set whenever Emacs asks the user which coding system
to use in order to write a file.  If you set it to nil explicitly,
then call `write-region', then afterward this variable will be non-nil
only if the user was explicitly asked and specified a coding system.

Defined in `international/mule-cmds'.
------------------------------------------------------------

But, it seems that it's not used by any code.  What is the
purpose of this variable?

This is the only changelog for this variable.
