[PATCH 3/3] nsenter: (man) correct the markup and improve the formatting

[Benno Schulenberg <bensberg@telfort.nl>]

Remove the mistaken angle brackets that were introduced last month
by commit f2a5997869, add the missing equals sign, and put both it
and the subsequent colon in bold as they are literal characters.

Also, indent the list of paths to make it clearer where it ends,
and so that the subsequent paragraph gets indented correctly.
