  It's a bug fix.

  In 2.x, the '?' character wasn't listed in "safe-characters".  Yet it
wasn't escaped.  That's wrong.

  The expansion functionality was re-written for v3.  It's now less
code, with better error messages, and fewer weird corner cases.  As a
side effect, the "safe-characters" is now processed correctly.
Previously, it wasn't.

  The "safe-characters" list is editable for a reason.  If '.' and '?'
should be listed by default, we can go fix that.  But the functionality
WILL NOT be reverted.  The old code was wrong.
