runtime(doc): correct `vi` registers 1-9 documentation error

When using heirloom `vi` originally written by Bill Joy (`:version`
gives me "Version 4.0 (gritter) 12/25/06"), its possible to store text into
registers 1-9 and subsequently use the `:edit` or `:next` command to
change files and paste the contents of those numbered registers,
contrary to what Vim documentation states.

POSIX description also does not mention such a restriction:
