Previously git-pull silently ignored the --verify-signatures option for
--rebase, potentially leaving users in the believe that the rebase
operation would check for valid GPG signatures.
Implementing --verify-signatures for git-rebase was talked about, but
doubts for a valid workflow rose up.
Since you usually merge other's branches into your branch you might have
an interest that their side has a valid GPG signature.
Rebasing, on the other hand, is you building something on top of
another's branch, essentially giving you the power to keep things sane.
If a valid use case is found, where --verify-signatures for git-rebase
looks sensible, that feature may be added then.
A warning was chosen in favor of emitting an error to prevent potential
breakage. A warning keeps things running, scripts for instance, while
still informing users about possibly unexpected behavior.

The warning message was changed to make it clear that the pull (and
rebase) operation still proceeds.
And the commit message was amended with more reasoning about the change
and why alternative approaches were not used.
