Broken link for fancy tag names with @

[szpak]

For example for this tag: https://github.com/jorgebucaran/hyperapp/releases/tag/@hyperapp/[email protected] (https://github.com/jorgebucaran/hyperapp/releases/tag/%40hyperapp%2Fevents%400.0.4)

an URL generated in the mail notification is: https://github.com/jorgebucaran/hyperapp/releases/tag/[email protected]

Probably some filter strips out @foo/ from a tag name.
