tags with spaces are printed as if multiple tags

[matt-incubet]

I've got an MQ patch called "refactoring for new design", and the commandline shows

[default ~3 qbase, qtip, refactoring, for, new, design mq: refactoring>

For one, obviously I'd like the tag to be printed as a single tag.

For two, since it's an applied MQ patch, it would be nice if it weren't listed as a tag at all.
