-** MAJOR BUG:
-** 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.
