Update pv to 1.6.0. Patch from Jonathan Buschmann in PR pkg/49795.

1.6.0 - 15 March 2015

	fix lstat64 support when unavailable - separate patches supplied by
Ganael Laplanche and Peter Korsgaard
	(#1506) new option "-D" / "--delay-start" to only show bar \ 
after N
seconds (Damon Harper)
	new option "--fineta" / "-I" to show ETA as time of day \ 
rather than
time remaining - patch supplied by Erkki Seppälä (r147)
	(#1509) change ETA (--eta / -e) so that days are given if the hours
remaining are 24 or more (Jacek Wielemborek)
	(#1499) repeat read and write attempts on partial buffer fill/empty to
work around post-signal transfer rate drop reported by Ralf Ramsauer
	(#1507) do not try to calculate total size in line mode, due to bug
reported by Jacek Wielemborek and Michiel Van Herwegen
	cleanup: removed defunct RATS comments and unnecessary copyright
notices
        clean up displayed lines when using --watchfd PID, when PID exits
        output errors on a new line to avoid overwriting transfer bar

Changes in older releases :

new option --watchfd
new option --null
new option --skip-errors
new option --format
new option --remote (-R) to control an already-running process
new option --line-mode (-l) to count lines instead of bytes
Fixes for AIX, Cygwin, Solaris, MacOSX
