Backport: Update documentation for indent-relative functions

Browse source 
* lisp/indent.el (indent-relative): Document what happens when there
  is no previous nonblank line.
* doc/lispref/text.texi (Relative Indent): Document
  indent-relative-first-indent-point instead of obsolete
  indent-relative-maybe. Fix documentation of which argument from
  'indent-relative' is used.
