pt-config-diff doesn't parse some comments correctly

[Scott Buchanan]

Command run:
pt-config-diff /etc/my.cnf h=localhost

pt-config-diff version: 2.2.16
MySQL version: 5.6.29

Contents of my.cnf, bisected to minimum causing problem:

    [mysqld]
    # (number of cpus * number of disks * 2)
    innodb_thread_concurrency=16

Output of pt-config-diff:

    Cannot determine if text is tabular, tab-separated or vertical:
    [mysqld]
    # (number of cpus * number of disks * 2)
    innodb_thread_concurrency=16

The line that is killing the process is the comment describing how to set innodb_thread_concurrency.
