+ for a component containing addresses, ADDRFMT, if COMPRESS is also
+ set, then addresses get split wrong (not at the spaces between commas).
+ To fix this correctly, putstr() should know about "atomic" strings that
+ must NOT be broken across lines. That's too difficult for right now
+ (it turns out that there are a number of degernate cases), so in
+ oneline(), instead of
+
+ (*onelp == '\n' && !onelp[1])
+
+ being a terminating condition,
+
+ (*onelp == '\n' && (!onelp[1] || (flags & ADDRFMT)))
+
+ is used instead. This cuts the line prematurely, and gives us a much
+ better chance of getting things right.
