vim-patch:8.2.1588: cannot read back the prompt of a prompt buffer

Browse Source 
Problem:    Cannot read back the prompt of a prompt buffer.
Solution:   Add prompt_getprompt(). (Ben Jackson, closes vim/vim#6851)
077cc7aa0e

Updated prompt_getprompt() doc to cb80aa2d53
and removed mention of method syntax usage (not supported by Nvim).
