[PATCH 7/6] emacs: relax tag syntax check in `notmuch-tag' function

[Dmitry Kurochkin]

The tag syntax check in `notmuch-tag' function was too strict and did
not allow nmbug tags with "::".  Since the check is done for all
tagging operations in Emacs UI, this basically means that no nmbug
tags can be changed.  The patch relaxes the tag syntax check to allow
any tag names that do not include whitespace characters.
