Isn't it already done for UTF-8 in the files you mentioned?
Both contain:

.if '\*[.T]'utf8' \{\
.  rchar \- - ' `
.
.  char \- \N'45'
.  char  - \N'45'
.  char  ' \N'39'
.  char  ` \N'96'
.\}

Tests did show that groff's HTML output of manpages does not look good and has 
bugs (results in wrong formatting). Well HTML formatted manpages are often 
processed by other tools (non-roff tools which just know the -man and -mdoc 
language). So changing groff's HTML should not be necessary--or there would be 
much more work to do beyond '-' and '\-'.
