This is difficult to read and understand. I presume you meant "no." as
shorthand for "number" but dropped the period. Even with the period,
it's still hard to read. Perhaps rewrite it as:
If 'lines' is greater than 0, print that may lines of...
or something.

Same problem. This literal "no" is quite confusing. Perhaps rewrite as above:
If lines > 0, print that many lines of...

ref-filter.h seems to be setting a precedent for overlong lines.
Wrapping this manually could improve readability.
