Checking minnie @ TUHS, I don't see it in /usr/man/man1/csh.1 in 3BSD,
2.9BSD (which actually came later), 4BSD, or 4.4BSD.  Given those
samples, I didn't check others.

Also I should retract a concession I made.  This patch doesn't regress
the typography on AT&T troff on typesetters (or nroff to whatever line
and daisy-wheel printers people still have in service)--that was an
assumption I made.  Rather, my patch improves it.

Looking closely at the original *roff, the reason is obvious (to those
poor souls trained in reading *roff):

.B \d\s+2\*^\s-2\u\fIstring1\fP\d\s+2\*^\s-2\u\fIstring2\fP\d\s+2\*^\s-2\u
.Q !!:s\d\s+2\*^\s-2\u\fIstring1\fP\d\s+2\*^\s-2\u\fIstring2\fP\d\s+2\*^\s-2\u

If those are supposed to be _superscripts_, they're backwards.  The
"move up half line" (\u) and "move down half line" (\d) escape sequences
are swapped.

Demonstrator man(7) document and PostScript output from DWB 3.3, Solaris
10, and Heirloom Doctools troffs attached.
