Description

If you give llog_reader an empty file to try to read it will loop until interrupted with the following:

Bit 0 of 135136 not set
Bit 0 of 135136 not set
Bit 0 of 135136 not set
Bit 0 of 135136 not set

It should, at most, print one iteration and exit. But perhaps an empty file should simply mean that llog_reader prints nothing.
