Dear Maintainer,

I ran:

     checklink https://www.google.com/

which produces a lot of lines:

	Use of uninitialized value $_ in pattern match (m//) at /usr/bin/checklink line 1296.
	Use of uninitialized value $_ in pattern match (m//) at /usr/bin/checklink line 1296.
	...

The problem was present for all other sites I tested. The output is below.
I also ran under 'env -i' to ensure my environment was not triggering this.

Alexis
