An ancient HTML spec (<URL: https://tools.ietf.org/html/rfc1866>)

        gives the URI of the head anchor of a hyperlink.

It refers to the URI spec (<URL: https://tools.ietf.org/html/rfc1630>):

    Partial (relative) form
       Within a object whose URI is well defined, the URI of another
       object may be given in abbreviated form, where parts of the two
       URIs are the same. This allows objects within a group to refer to
       each other without requiring the space for a complete reference,
       and it incidentally allows the group of objects to be moved
       without changing any references.


       The rules for the use of a partial name relative to the URI of
       the context are: [...]

Bottom line: you are safe.
