It probably makes sense to continue to have the warning in the dry-run
case, but it may make sense to tweak it grammatically when we are in
dry-run mode. Saying "would stage removal" is technically correct, but I
think it is somewhat ambiguous: would git do it if we were not in a
--dry-run, or would git do it if it were Git 2.0?

Doing it as:

  warning: not staging removal of '%s'

could work for both cases. Something like "not considering" (or another
synonym for "considering") might be even more accurate. It is not just
that we did not stage it; it is what we did not even consider it an item
for staging under the current rules.

Note that the "not staging" warnings may potentially be interspersed
with the normal dry-run output. I think that's OK. But another
alternative would be to collect the paths and then print:

  warning: In Git 2.0, ...

  The following deleted paths were not considered under the current
  rule. Use "git add -A" to stage their removal now.
