>Description:
the info doc for CVS says that punching in `cvs update -D...' implies -P,

However after testing, it looks like -P needs indeed to be specified for empty directories to be culled out (so I suppose either one is wrong: the doc or the behavior ;p)

from googling quickly around it looked like -P is implied *only* for check-out



>How-To-Repeat:
the problem is in the documentation

What I did is run `cvs update -CD 20210101 -d' in `/usr/src/usr.bin/ktrace' expecting the ktrace sub-directory to go away.  It only did after specifying `-P'

Meanwhile, §A.24.1 (update options) of the cvs info document states:

<<`-D date'
     Use the most recent revision no later than DATE.  This option is
     sticky, and implies `-P'. >>
