In addition to matching stripped refs, one can now add hideRefs patterns
that the full (unstripped) ref is matched against. To distinguish
between stripped and full matches, those new patterns must be prefixed
with a circumflex (^).
This commit also removes support for the undocumented and unintended
hideRefs settings "have" (suppressing all "have" lines) and
"capabilities^{}" (suppressing the capabilities line).
