rewrite.
* gash/compat/srfi-43.scm (vector-empty?): New procedure.
* gash/pattern.scm (pattern-null?): New procedure.
* gash/word.scm (qword->pattern-string): New procedure.
(qword->pattern): Rewrite using 'qword->pattern-string'.
(find-files): New procedure.
(expand-pathnames): Rewrite using 'find-files' and add a docstring.
* tests/unit/word.scm: Add tests.
(mock): New syntax.
(make-pure-scandir): New procedure.
(with-mocked-files): New syntax.
* gash/compat/srfi-43.scm: New file.
* Makefile.am: Add it.
* gash/pattern.scm (<pattern>): New record type.
(parse-part): New procedure.
(parse-pattern): Return a '<pattern>'.
(pattern-plain?, pattern-match?): Accept a '<pattern>'.
(string-starts-with-part, string-ends-with-part,
string-contains-part): Treat 'part' as a vector.
