tags: don't allow tags to begin with a '/'.

Browse Source 
Disallow tags from starting with a '/' character. This is so that tag
abbreviations in autocomplete, which start with a '/', don't conflict
with regular tags.

Also disallow some other punctuation characters: `%{})]. Currently no
tags start with these characters. This is to reserve other special
characters in case we need them for other future syntax extensions.
