This is not likely to be true of other signing schemes.  In fact, other
than OpenPGP, PEM, and CMS (S/MIME), this is probably not true at all.
I know OpenBSD's signify has no wrappers (except a mandatory "untrusted
comment:" line at the beginning).  There wouldn't be a way to match such
a signature unless we implemented prefix or regex support.

It's currently possible to hack other signatures in with wrappers if
they wrap the actual signature in OpenPGP-like armor; someone (I believe
Eric Wong) has gotten this to work with signify.  I only mention signify
because other than OpenPGP and CMS, it's the only scheme I've seen
people use with Git.
