This function inserts a tag or extension into a file name. It can also replace an element of a file name.

By default, tags are inserted at the ultimate position and extensions
at the penultimate position, if possible.
(That is, the final file extension will not change, unless the insertion
position is specified otherwise or the orginal file name had no extension.)
If replace is TRUE, the tag at the indicated position is
replaced by the new tag instead.
