[mdoc]: Address Savannah #65763 (`\?` comparison).
* tmac/doc.tmac (Bd): Fix code style nit. Perform "strict" string
comparison when using formatted output comparison operator to peform
matching on macro argument. See subsection/node "Operators in
Conditionals" in groff's Texinfo manual.
See <https://savannah.gnu.org/bugs/?65763>.
groff.info:
Surround the comparands with '\?' to avoid formatting them; this
causes them to be compared character by character, as with string
comparisons in other programming languages.
.ie "\?|\?"\?\fR|\fP\?" true
.el false
=> false
Since GNU 'troff' reads comparands protected with '\?' in copy mode
(*note Copy Mode::), they need not even be valid 'groff' syntax.
The escape character is still lexically recognized, however, and
consumes the next character.
