pt-log-player creates an extra session directory
If I invoke pt-log-player as follows:
%> pt-log-player --split Thread_id --session-files 1 --only-select FILENAME
It creates two directories: ./1 and ./2 as well as two files: sessions-1.txt and sessions-2.txt. ./1 and ./2 both have content, as does sessions-1.txt, but sessions-2.txt does not. Why are sessions-2.txt and ./2 created when I have clearly only asked for one session?
