unicode hyphen in man page instead of ASCII hyphen-minus about scrot HOT 2 OPEN

Apparently, groff recently stopped fixing the issue of broken man pages and reverted to original AT&T behaviour and this is the reason why this bug is only now being recognized:
https://lwn.net/Articles/947941/

from scrot.

The scrot manpage gets generated by txt2man. Manually adding \ in front of a hyphen in man/scrot.txt does not work correctly. The resulting manpage gets severely messed up:

Applying some sed post-processing in man/create-man.sh to turn each - into \- works:

 function create-man {
-txt2man -d "$T2M_DATE" -t $T2M_NAME -r $T2M_NAME-$T2M_VERSION -s $T2M_LEVEL -v "$T2M_DESC" $T2M_NAME.txt > $T2M_NAME.$T2M_LEVEL
+txt2man -d "$T2M_DATE" -t $T2M_NAME -r $T2M_NAME-$T2M_VERSION -s $T2M_LEVEL -v "$T2M_DESC" $T2M_NAME.txt | sed 's|-|\\-|g' > $T2M_NAME.$T2M_LEVEL
 }

This will of course turn every - into an ascii hyphen. But IMO that's fine. Unicode hyphen doesn't have any practical purpose in manpages anyways.

What I'm wondering now is whether this change should be made on our end or if this is something that should be done in txt2man instead.
