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
1
1
I think it should be fixed as following. Please check it.
