rcd@opus.UUCP (Dick Dunn) (10/30/84)
I recently discovered that nroff underscores text (as when it's doing its
"italic" font) with '_' followed by \b followed by the character. The
thing that seems odd is that it uses, literally, '_'. It DOESN'T use the
character given for '_' in the mapping table (in /usr/lib/term/tabxyzzy),
nor does it use \(ru (rule) or \(ul (underrule)--the char constant is
hardwired into the code.
(This is on a 4.2 system, to the extent that might matter.)
Any idea why it's done this way? In particular, any idea whether it was
intentional or just lazy?
