updated for version 7.3.102

Problem:    When using ":make", typing the next command and then getting the
            "reload" prompt the next command is (partly) eaten by the reload
            prompt.
Solution:   Accept ':' as a special character at the reload prompt to accept
            the default choice and execute the command.
