Clean up trailing whitespace.

MFC of 250710: (delete addition of -k which does not exist in 8-stable)

When running the -m option to generate a newfs(8) command suitable for
recreating the filesystem, check for and output the -i, -k, and -l
options if appropriate.

Note the remaining deficiencies of the -m option in the dumpfs(8)
manual page. Specifically that newfs(8) options -E, -R, -S, and -T
options are not handled and that -p is not useful so is omitted.
Also document that newfs(8) options -n and -r are neither checked
for nor output but should be. The -r flag is needed if the filesystem
uses gjournal(8).
