+Subject: [PATCH] Don't write options without value to pwquality conf
+ (#1618865)
+
+Per https://bugzilla.redhat.com/show_bug.cgi?id=1618865 , it is
+incorrect to write lines like this in a pwquality config file:
+
+minlen=
+minclass=
+maxrepeat=
+maxclassrepeat=
+
+There should either be an actual integer value, or the line
+should be omitted entirely. Including the option with no value
+is wrong and breaks pwquality. This should fix the problem by
+only writing the lines if the option is actually set.
