Counting code - Ohcount vs Cloc

We have lots of evil csh which we want to convert to bash or even perl or python. So I decided to test some code line counting tools to estimate the effort involved in terms of pure lines of code. I tested 2 options: the old and venerable cloc and the child of web 2.0 ohcount. Like the definition of the metre, what constitutes a line of code can vary a bit.

Cloc gives similar numbers off by a few thousand and separated by csh vs bash. Ohcount could do with some more shell script discrimination.
