Continuing what's turning into an epic one-man list-noise generation
effort, I did a bit more digging and it looks like notmuch-hello
generates the list of tags for the 'All tags' view by processing each
line returned by 'search-tags'.

A call to 'notmuch search-tags' from the command line does indeed return
an empty string as the first entry for me[1].

Does that point to bad data on my part, or has the output of
'search-tags' changed recently?

If the former, any thoughts on how I differentiate an empty tag from
something untagged in a search so I can prune it?


[1] So we have an apparently empty tag being concatenated with a search
    string of 'tag:', which actually gives us a search for every message
    containing the word 'tag' rather than a tag-based search.
