PIDs can vanish (exit) from /proc/ between gathering the list of PIDs and getting all of their stats. * Ignore file not found errors. * Explicitly count the PIDs we find. * Cleanup some error style issues. Signed-off-by: Ben Kochie <superq@gmail.com>

Just use %s or %v for error type formatting (but %q is good to quote file names embedded in a string).

This is an issue all over the codebase. I filed #1044 to do cleanup.

It seems like all the other %q I found are legit - %q makes sense when you actually want to quote something, but when you have a final colon and then an entire error string following, it doesn't make sense to quote that.
