I'm not sure how ViewCVS and PCL-cvs run the diff command, but here's a clue.
Suppose you update your sandbox and main.f 1.9 is the version you get. If
you run "cvs diff main.f" you will see that there are no differences.
That's to be expected.
Someone checks in a revision to main.f, producing version 1.10. Now, if you
run that same cvs diff command again, you will still get no differences!
That's surprising until you remember that the diff command compares the
local file with the version in the repository (1.9) that it's based on. To
see the differences between the local file and the head version you need to
use the command "cvs diff -r HEAD main.f".
So, if your tools are using the "cvs diff main.f" command, then the output
you see is correct.
