Hi, spawning from the realization that tags are pretty much unconstrained in what they can contain (newlines, whitespace, a solo '-' which you can add but not remove, etc.) there was some talk on IRC about restricting them. Notmuch, but a little. This patch does just that. Perhaps it should be in lib rather than cli, but it's a start for a discussion on what's an acceptable tag really. BR, Jani.
