man page is wrong

[Thiago Jung Bauermann]

Hi,

The CVS man page says that the -D option to the update command implies
-P, but I find it to be different in practice. This can be demonstrated
with the GDB CVS repository:

1. Checkout anonymous GDB CVS tree as instructed here:

http://sourceware.org/gdb/current/

2. After the checkout, verify that the directory libdecnumber exists and
has source code files in it.

3. Go back some months:

$ cvs update -D 2007-05-05

4. Note that the libdecnumber directory exists but has no source code
(just two subdirectories, which also don't have source code).

5. Update using -P option this time:

$ cvs update -D 2007-05-05 -P

6. Note that there is no libdecnumber directory anymore (which is
correct).

Since results from step 4 and step 6 are different, -D does not imply -P
as the man page says. I don't know whether the CVS behaviour is wrong or
the man page is wrong.

This is with CVS version 1.12.13.
