fs_usage tool: How to output *full* pathnames

I'm using fs_usage on Mac to dump my app's file accesses to a text file. The only problem is that only a truncated version of the path is output. This is pointed out in the man page, but there appears to be no option to show the full file paths in the output (at least when I redirect it to a file: I've run it purely in the terminal and it output proper paths). I have a lot of directory structures in which the final few path components look very similar, but they are from different parent directories.

It would appear that fs_usage is limited to ~253 characters of output, suggesting that it may be hardcoded with hardcoded 255 or 256 char limit.

The GUI tool fseventer does not suffer such a limit, you may also try fslogger.
