patch 8.1.0439: recursive use of getcmdline() still not protectedv8.1.0439

Problem:    Recursive use of getcmdline() still not protected.
Solution:   Instead of saving the command buffer when making a call which may
            cause recursiveness, save the buffer when actually being called
            recursively.
