[1.0 release prep] Remove tilde expansion discipline

Browse source 
Defining a .sh.tilde.get or .sh.tilde.set discipline function to
extend tilde expansion works well as long as the discipline
function doesn't get interrupted (e.g. with Crtl+C) or produce an
error message. Either of those will cause the shell to become
unstable and crash.

This feature is now removed from the 1.0 branch as it is not ready
for prime time. It can return to a release branch if/when we manage
to fix it on the master branch.

- Tilde expansion can now be extended or modified by defining a .sh.tilde.get
or .sh.tilde.set discipline function. This replaces a 2004 undocumented
attempt to add this functionality via a .sh.tilde built-in, which never
worked and crashed the shell. See the manual for details on the new method.
- Fixed a bug in interactive shells: if a variable used by the shell called
a discipline function (such as PS1.get() or COLUMNS.set()), the value of $?
was set to the exit status of the discipline function instead of the last
