Link to tabs CSS assumes root folder installation causing "/sites/.../all/modules/jstools/tabs/tabs-ie.css not found"

In tabs.module, line 129, it states:

But it should be:

i.e. the href should not start with a "/". This causes no immediate obvious issue but for every page viewed if your Drupal installation is not in your root public_html folder it generates an error, something like "/sites/.../all/modules/jstools/tabs/tabs-ie.css not found".

Hopefully I've identified the fix correctly in this post, and if so it can be included in the next drop.
