} This violates our own documentation:

You're sort of correct, but you quoted the wrong section of the doc.
The relevant bit is this, under parameter expansion:

 In the expansions discussed below that require a pattern, the form of
 the pattern is the same as that used for filename generation; see *Note
 Filename Generation::.  Note that these patterns, along with the
 replacement text of any substitutions, are themselves subject to
 parameter expansion, command substitution, and arithmetic expansion.

That paragraph should include "filename expansion" (but not generation)
among the list of things to which the patterns are subject.  So

	${foo##~}

removes the home directory from $foo.
