Reduce instances of `` '' in manuals.

troff displays these as typographic quotes, but nroff implementations
almost always print them literally, which rarely has the intended effect
with modern fonts, even in stock xterm.

These uses of `` '' can be replaced either with more semantic alternatives
or with Dq, which prints typographic quotes in a UTF-8 locale (but will
automatically fall back to `` '' in an ASCII locale).

fix KRL generation when multiple CAs are in use

We would generate an invalid KRL when revoking certs by serial
number for multiple CA keys due to a section being written out
twice.

Also extend the regress test to catch this case by having it
produce a multi-CA KRL.
