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.

This command indents the current line like the previous nonblank line,
by calling @code{indent-relative} with @code{t} as the
@var{unindented-ok} argument. The return value is unpredictable.
@var{first-only} argument. The return value is unpredictable.
If the previous nonblank line has no indent points beyond the current
column, this command does nothing.
