Pattern matching applies primarily to pathname expansion; other uses
explicitly refer to its use there:
              The pattern is expanded to produce a pattern just as in
              pathname expansion.  Parameter is expanded and the
              longest match of pattern against its value is replaced
              with string.  [...]
