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