Description of problem:
I believe I have found a bug in fmt, one of the textutils programs. 
Here's the script:
#!/bin/bash
for i in $(seq -w 4052 1 4053) ; do 
  echo -n "$i: " ; seq -w 0 10000 | fmt -w $i | head -1 | wc
done
 Notice the drop in word count (631 -> 321) even though the 
width option to fmt was increased by one.
 Here's a similar version where you can see the ouput:
#!/bin/bash
for i in $(seq -w 4052 1 4053) ; do 
  echo -n "$i: " ; seq -w 0 10000 | fmt -w $i | head -2
done 

No data is lost. fmt is just splitting earlier than expected.


Version-Release number of selected component (if applicable):
  textutils-2.0.11-7

How reproducible:
Always

Steps to Reproduce:
1.see description for mini script
2.
3.
	

Actual Results:  fmt split earlier than expected

Expected Results:  a longer line
