Now this simply replaces the \in, \at and \about macro's with one that does not show on the page where the link originates, but behaves as of old everywhere else. I introduced the unskip in order to remove the space that ruins the end of a line when there is nothing to display. For example from \in{see there}[ref]. <--this period would otherwise acquire a space before it.

Instead of \unskip you should use \removeunwantedspaces which does a check before it calls \unskip.

Don’t redefine \in, at and \about because all three commands can also be used in math mode where they have a different meaning but with your redefinition they can’t be used anymore for math.
