Description of problem:

pbmclean and pbmlife will not run on images of any size.

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

netpbm-progs-10.35.58-1.fc9.i386

How reproducible:

Every invocation of pbmclean or pbmlife.

Steps to Reproduce:

pbmmake 1 1 | pbmclean > /dev/null

or 

pbmmake 1 1 | pbmlife > /dev/null

Actual results:

Both programs will exit with the error: "progname: EOF / read error reading a one-byte sample"

Expected results:

A 1x1 PBM image, transformed as appropriate.

Additional info:

Both programs employ read-ahead because they transform pixels in an image by counting their neighbours. However, the patch netpbm-10.23-security.patch has mistaken the meaning of the "had enough rows" tests for read-ahead in both cases.

For example, the security patch has changed a test in pbmclean.c from:

(row+1 < rows) --> (row <= rows)

which is clearly not the same test, and a similar line in pbmlife has been corrupted. As the security patch only affects this one test in both files, I have tried fixing it by removing the changes to pbmclean.c and pbmlife.c from the security patch, and the programs work as expected.
