commit 85d248e5e5c3a105769a465d8884ba351294c798
Author: G. Branden Robinson <[email protected]>

[troff]: Fix spurious "delim" warning.
* src/roff/troff/input.cpp (token::is_usable_as_delimter): Fix spurious
warning in category "delim" when using a tab character as an escape
sequence as a delimiter. AT&T troff allows that, and so has GNU troff
historically.
Continues commit 39c1176bfa, 25 January. See Savannah #66686 and
Savannah #66526.

troff:<standard input>:1: warning: interpreting a tab character as an
escape sequence delimiter; it is ambiguous because it can also begin a numeric
expression
