+From: Jean Delvare <jdelvare@suse.de>
+Subject: compat/getopt: Allow non-digit parameter embedded in short option
+
+The compatibility getopt script allows only digit parameters to be
+embedded in short options. Util-linux's getopt implementation does
+not have such a restriction and allows any parameter to be embedded
+in short options. As a consequence, using the compatibility getopt
+script would choke for example on "-pab", which is a legal option
+of the "quilt refresh" command.
+
+Remove the limitation on digits so that the compatibility getopt
+script allows what util-linux allows. This fixes the second half
+of bug #54772:
+https://savannah.nongnu.org/bugs/index.php?54772
+
+As a side note, this feature of the compatibility script was broken
+anyway, as it would output the digits in reverse order.

+From: Jean Delvare <jdelvare@suse.de>
+Subject: compat/getopt: Handle a second separator
+
+getopt can be passed 2 '--' separators. The first one tells that
+getopt options are over and target program options start. The second
+one tells that the target program's options are over and following
+arguments should be treated as non-options even if they look like
+options.
+
+This second separator was not handled, causing the compatibility
+getopt script to treat the following arguments as options, eventually
+failing one way or another.
+
+Properly detect and handle the second separator. This fixes the first
+half of bug #54772:
+https://savannah.nongnu.org/bugs/index.php?54772
