I looked a bit around, and found that these strings are copie= d verbatim from the *.by files.Looking at the comments of lread.= c, this seems to be a limitation of the reader: "Because it's more= difficult to peek 2 chars ahead, a new-style=C2=A0,@ can still not be used= outside of a `, unless it's in the middle=C2=A0of a list."<= div>Not sure what to do with this, though. Changing the reader would introd= uce a breaking change for no good reason, since we're trying to get rid= of old-style backquotes. So I think this should rather be fixed in Bovine,= either by escaping the offending commas, or by removing the space between = ( and ,.
