- by grepping over src/share/termcap/termcap.src (dg460-ansi, wy60,
wy60-25, wy60-42, and wy60-43 have these),
- by looking over in the contrib/ncurses/ncurses/tinfo/comp_scan.c
_nc_trans_string() code,
- by running the test with the ncurses' stock read_termcap.c,
- by seeing how tic(1) converts colons,
- by hearing the following from Thomas Dickey (ncurses maintainer):
: ncurses handles the escaped colon
: fine, but how it's interpreted by FreeBSD's termcap library is another
: matter altogether.
- by POLA.
I know the termcap(5) mentions that `:' in the value should be written
as \072, I just think that not supporting `\:' is a bug, and the above
is a compiled list of why I think so.
