* and # behave differently with counts

[danth]

Say we start on [ at the end of line 2, and find a path to the beginning of "weight" on line 13.

https://github.com/AlphaMycelium/pathfinder.vim/blob/59a07b40981cec9f5f12c6472b8065bc328731d7/plugin/main.vim#L1-L14

The pathfinder returns 2*. That is made from:

• * to search for the next [ (on line 12)
• * again to search for "weight", which moves down to the next line

However, running 2* instead of ** causes [ to be searched twice, and ends up somewhere else.
