 I think it should be fixed as following.  Please check it.

getregtype() works differently from what is documented for empty or unknown register

[Yukihiro Nakadaira]

According to :help getregtype(), it returns 0 for empty or unknown
register.  But it returns  for empty register.  And it returns unnamed
register's type for unknown register.

Steps to reproduce:
  $ vim -u NONE -i NONE
  : test for empty register
  :echo getregtype('a') is ''
  : test for unknown register
  :echo getregtype('^') is ''
  :call setreg('', 'v')
  :echo getregtype('^') is ''

Result:
  1
  1
  0

Expected:
  1

I think it should be fixed as following.  Please check it.
