the large file challenge

[Sadhunathan Nadesan]

| 
| One last note:
| 
| Be careful of using <read from file xxx for yyy>
| 
| If you do not read for "lines", you run the risk of cutting a line in half on 
| the spot where your magic string occurs.
| 
| So always use <read from file xxx for yyy LINES>
|

	Good point.  For this particular use of the
	program a close count is ok - no problem if
	it's not perfect but clearly, that might matter
	in other instances.

	It is interesting that the different algorithms
	are varying slightly with the count, probaby
	for reasons like you mention.
