Subject: 30.0.50; set-justification-center joins lines before centering
Date: Tue, 03 Jan 2023 13:56:50 +0300

When I have following lines in text-mode:

MY FIRST LINE
SECOND LINE
THIRD LINE

and do M-x set-justification-center

I get following unexpected circumstance:

		 MY FIRST LINE SECOND LINE THIRD LINE

Description of the function does not say it is going to join lines. My
expectation is not that it should join lines but center lines only.

Same problem is happening with set-justification-right

And me as user I need to make double lines, do the command on each of
the line, cumbersome work, and then join lines manually to avoid the
above happening.

All justification functions work on full paragraphs.

If you want to center a single line, use center-line.

The doc string says:

  Make paragraphs in the region centered.

A paragraph in Emacs is (by default) delimited by empty lines.  So the
above is a single paragraph, and the doc string seems to be correct
and accurate.

Eh, thanks!

Is there right justify for line?

Thanks.

I must make right-justify for me.
