PCRE and PCRE2 also tend to have a lot of security updates, so I would
prefer if we didn't import them into the tree.  It is far better for
users to use their distro's packages for PCRE, as it means they get
automatic security updates even if they're using an old Git.

We shouldn't consider shipping anything with a remotely frequent history
of security updates in our tree, since people very frequently run old or
ancient versions of Git.
