How to append a character while using the conditional statement in sightly?

Question

I need to set the href value depending on the nullity of sling:vanityPath. The hit.properties.sling:vanityPath returns the string value for sling:vanityPath property. I need to append a '/' before the hit.properties.sling:vanityPath value. Is it possible to do that in the following code or do I have to test it twice, but that comes with code repetition?

The prependPath could be used to do this.

prependPath - prepends its content to the path that identifies a resource

${'path' @ prependPath='..'}
<!-- outputs: ../path -->

${'path' @ prependPath='/', appendPath='/'}
<!-- outputs: /path/ -->

${'http://example.com/path/page.html' @ prependPath='foo'}
<!-- outputs: http://example.com/foo/path/page.html -->
