Subject: This patch breaks tests and is irrelevant now

Note that this patch breaks an existing test (since 2001), namely

(option-ref (getopt-long
              (list "prog" "-f4")
              '((foo
                 (value optional)
                 (single-char #\f))
                (bar)))
             'foo #f)

bails out with 

prog: no such option: -4

The only way to deal with this is to give getopt-long more intelligence in determining where command-line arguments are option
values or otherwise; this is the subject of #40719 which also allows numerical short options, but doesn't break the test suite.

My suggestion would be to dismiss (close) this bug report at this time.
