cvs queries, possibility of bugs

[Paul Edwards]

CVS Version: 1.11.2

Question 1
If I go:
cvs diff -r rel1 -r rel2
in a directory, I get notification that a diff is being done, and it is
empty,
on files that are identical, but due to branching history, happen to have
different version numbers.  Is there a way of making it silent?

Question 2
If I do:
cvs diff -r rel1 -r rel2 nonexistant.c
then because both tags are valid, I don't get notified that I made a typo
in the filename, even when it is clearly not in the repository.  Is there a
way of getting notified when I do a non-sensical command like this?

Question 3
I would like to do a "cvs rdiff" and get the same output that I normally
get
from doing a normal "cvs diff".

Question 4
When I do a "cvs log -b" in a directory with a sticky tag, I would expect
the
output to be the equivalent of "cvs log -rsticky_tag" but instead it
ignores
the sticky tag and goes for the import branch.  I would have thought that
"-b" would go for the sticky tag (if present).  Is there any way of getting
the
sticky tag to be used, besides typing it on every command?


Note: Because of questions (1) and (3) I actually end up doing two exports
and using the unix "diff -r" to produce diff listings.


Thanks.  Paul.
