Maybe diff's -N option is of help here. It creates "diffs
against /dev/null" for nonexistent files. This will make new
files show up with all their content in the diff and show when
all the content of an obsoleted file vanishes.
A quick glimpse over the "man diff patch" output (searching for
"creat" and "remov") reveals that patch(1) can create new files
when fed with "diff -N" output and has an -E option to remove
files with null content. Question is: How "legal" are zero
length files under the given circumstances? I.e. will this
remove files which ought to be there but empty? I feel chances
for this are quite low. And those files are removed only when
they get patched to empty content.
It turns out diff(1) should get passed the -N option by default
just as one doesn't think about using -u. It will not harm and
can be of use only. This is something the user has to train
itself into or has to add another alias for. BTW "cvs -H diff"
(on a 4.1-S system) tells you the builtin diff knows -N, too.
Adjusting ~/.cvsrc will suffice once and for all. :)
