continuous igor checking

[Li-Wen Hsu]

Some of you might know this CI job:

https://jenkins.freebsd.org/job/FreeBSD_Doc-igor/

I am embarrassed that I found it reports "everything is fine" falsely
for a while, and don't have time to fix it.  Well, I just got it fixed
at the documentation working group at BSDCan. :)

So, please check on "Checkstyle Warnings" link on the left menu of that
job and let's get these fixed.
