What I'm getting at is that a tag is not _just_ an alias for a revision number,
and you shouldn't have to convert it to a revision number in order to use it in
common situations. You should be able to specify it directly in the command -
not within the "--revision" parameter, because it isn't just a revision, but
somewhere in the command.
For my example of where you don't have to manually convert it to a revision
number, I'll find the difference between "foo.c" as it was at tag TAG1 and now:
svn diff --old=$TAGS/TAG1 --new=. foo.c
I'll admit again that this syntax is not quite as brief as you might want, but
it's not grossly inappropriate either, is it? Also, I'll admit again that
using an environment variable like that is flakey and not really acceptable in
more complex situations, but that's irrelevant to the argument that the user
needs to translate the tag to a revision number manually.
