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