Copy Mode in Vr2 (at least) troff does not work as documented.  According
to Ossanna, the only bash-interpretations in Copy Mode are \n, \*, \$,
\NEWLINE, \", \t, \a, \., and \\.

According to the source code, \e, \ , \|, \^, \{, \}, \', \`,
\_, \-, \&, \c, \!, \%, and \g are translated as well.  That is, they
are interpreted as escapes, though the escape functions are not performed
at once.

Repeat by:
	.de W
	This is a bashdash \-.
	..
	'\" Disable bash-escaping.
	.eo
	This is a bashdash \-.
	.W

Since this bug or feature interferes with the .ec/.eo feature, it ought
to be documented.  (I discovered it while writing a dump-macro macro.)
