+** MAJOR BUG:

+** 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.
