There are some fairly conservative default thresholds configured
at present.  In particular, `so-long-max-lines' is currently set
to 5, meaning that, following any initial comments/whitespace,
only the first 5 lines will be checked.

I would guess that in the case of this second file, the long lines
did not occur until after that default threshold?

Check M-x customize-group so-long for config options.

I am completely open to changing the default values.  I have never
had a firm idea of what they should be set to by default.
