svn commit: r294861 - head/usr.bin/dpv

New Revision: 294861
URL: https://svnweb.freebsd.org/changeset/base/294861

Log:
  Add `-k' for dpv(3) `keep_tite' config option
  
  For scripts using dialog(1) several times, it can be visually distracting
  running dpv(1) several times amidst other dialogs. The `-k' option, similar
  to dialog(1) `--keep-tite', enables the same functionality to smooth ti/te.
