+If some text environment body is too long to fit on a line, @LaTeX{}
+will insert line breaks that avoid hyphenation and avoid stretching or
+shrinking any interword space.
 
 This environment inserts space above and below the text body.  See
 @ref{\centering} to avoid such space, for example inside a @code{figure}
 environment.
 
-In this example, depending on the line width, @LaTeX{} may choose a break
-for the part before the double backslash, will center the line or two,
-then will break at the double backslash, and will center the ending.
+This example produces three centered lines.  There is extra vertical
+space between the last two lines.

+In this example, depending on the page's line width, @LaTeX{} may choose
+a line break for the part before the double backslash.  If so, it will
+center each of the two lines and if not it will center the single line.
+Then @LaTeX{} will break at the double backslash, and will center the
+ending.
