Maybe it's a little more complicated.

When you add characters to 'isk' with the star command `*'
and again remove them when going to a tag with Ctrl-],
then suddenly `#foo' is no longer found, because the pattern
\<#foo\>
ceases to match (`\<' only matches before an 'isk' character).
Searching for
#foo\>
instead should be fine.

almost got a plugin out of this
