Remove useless uses of cat, and replace with filename arguments

Replace uses of cat that do nothing but writing the contents of
a single file to another command via pipe.

[jc: Original patch from Josh was somewhat buggy and rewrote
"cat $file | wc -l" to "wc -l $file", but this one should be Ok.]
