o with ^ on top of it

[Alejandro Colomar]

Hi,

The following code (found in regex.7) wants to represent an 'o' with a 
'^' on top of it (.  Is that code correct?  It's working on the PDF 
(although it's ugly), but not on the terminal.  It was changed by a 
commit that changed ^ by \(ha for compatibility, but I'm not sure if 
that's correct in this specific case.


$ cat bs.man
.TH a s d f
.SH Backspace
foo "\fI[[=o=]]\fP", "\fI[[=\o'o\(ha'=]]\fP",


$ groff -Tascii -man ./bs.man | grep -v '(s)'

Backspace
       foo "[[=o=]]", "[[=^=]]",


$ groff -Tascii -man ./bs.man  | grep -v '(s)' | cat -v

^[[1mBackspace^[[0m
       foo "^[[4m[[=o=]]^[[24m", "^[[4m[[=o^H^=]]^[[24m",


Thanks,

Alex
