svn commit: r362435 - head/usr.bin/seq

New Revision: 362435
URL: https://svnweb.freebsd.org/changeset/base/362435

Log:
  seq(1): complete EXAMPLES section
  
  * Add a small description before the EXAMPLES that are already in the man page
    to explicitely state what we are trying to show instead of having the user
    guess what the example is doing.
  
  * Add two more examples to show usage of -s, -t and -f
  
  * mandoc -Tlint reports irrelevant use of .Tn so remove them since according to
    mdoc(7) it is there only for compatibility and should not be used in new
    manuals.
