bug#65819: 29.1; Incorrect description about return value

[Ikumi Keita <ikumi@ikumi.que.jp>]

The elisp reference info node `(elisp) Motion by Indent' states that
`backward-to-indentation' and `forward-to-indentation' return nil.
However, they actually return non-nil value.

Either the description in the elisp reference or the implementaion of
the commands should be corrected.

,----[ (elisp) Motion by Indent ]
|  -- Command: backward-to-indentation &optional arg
|      This command moves point backward ARG lines and then to the first
|      nonblank character on that line.  It returns ‘nil’.  If ARG is
|      omitted or ‘nil’, it defaults to 1.
| 
|  -- Command: forward-to-indentation &optional arg
|      This command moves point forward ARG lines and then to the first
|      nonblank character on that line.  It returns ‘nil’.  If ARG is
|      omitted or ‘nil’, it defaults to 1.
