Hello,

This patch adds two missing entries into the Parameter Expansion's subsection
on Case Modification of the Bash man page.

Problem:
   The "Parameter Expansion" section of doc/bash.1 currently does not
   document the behavior of the `${parameter~pattern}` or
   `${parameter~~pattern}` operators.

The case toggling word expansions are rather famously undocumented. I don't
like the syntax and I don't encourage its use. Those operators are still
there to support scripts that use them.
