Unfortunately, that hits on a certain limitation.
It will fail in certain circumstances, that is.
That is, because TM will match whitespace characters and the starting
brackets of HTML tags as Current word as well.

I did some ctrl W on such arbitrary strings, to verify this, and this
occurs to happen even on lines, that only have white-space characters.

I wonder, if this is expected behavior, however I managed to get around
this with some replacement patterns on the variables.
This works, but not if I trigger the macro in front of another Tag.
Then in this case, it will pull in the starting bracket of the following
tag and take that as Current word and thus spoil the empty Current word
variable.
