Support counts like all native tag nav mappings do#22

On second thought, this should maybe have the execute in a try with the reset in its finally. Though perhaps that's overly defensive when it's an internal function and we're reasonably certain it's called with safe operations.

When trying to jump to a non-existing tag, that seems to be reported as an error (E426). I'm not sure how that behaves wrt finally. Maybe you can test with that to decide whether finally is needed.

Ah yes, my intuition was coming from somewhere 😄
It turns out that the 'previewheight' value was restored on error (because execution continued, :h except-compat), but there is another reason to catch the error: it leaves behind a spurious preview window of the current buffer, as if you'd run :pedit with no argument. Fixed.
I can squash these changes later if desired, just going to leave it until further review.
Generalizes the approach so that the function doesn't need logic to handle split, preview, etc. Also no longer results in the cursor being moved to beginning of the function call (or record/macro after vim-erlang#15) in the original buffer.
Vim's native window tag mappings (split- and preview-related) use count to affect the size of the new window. Regular mappings like `CTRL-]` use count to jump to a match index like `:tag` does. These changes mimic all of the above behavior accurately with this plugin's enhanced notion of tag identifiers for Erlang.

This is based on my branch from #21 because it includes support for the preview window mappings, but since it's a more substantial change I thought it made sense to review this independently.
