Problem:  When updating the window involves a regexp pattern, an
          interactive substitute to replace a "\n" with a line
          break fails. (Ingo Karkat)

Solution: Set reg_line_lbr in vim_regsub() and vim_regsub_multi().

vim-patch:7.4.260

Problem:  It is possible to define a function with a colon in the name.  It
          is possible to define a function with a lower case character if a
          "#" appears after the name.
Solution: Disallow using a colon other than with "s:".  Ignore "#" after the
          name.
