'To:' field in new posts via NNTP

New messages (not replies) posted to an echoarea via NNTP display the Newsgroup Name (from SCFG) as the recipient, instead of "All". For example, "To: fidonet.FIDOTEST", that looks odd on echomail (at least to me). Any reason for this?

I fixed this in my mod by editing nntpservice.js and changing:

if(hdr.to==undefined && hdr.newsgroups!=undefined)
    hdr.to=hdr.newsgroups; 

to

if(hdr.to==undefined && hdr.newsgroups!=undefined)
    hdr.to="All";

(For reference, that sentence was introduced in commit 0eb7d78a )
