The new 5.8.0 tag parser generates empty text words that can break layout

[dapetcu21]

Stuff like this happens:

Printing out the generated words table, I notice there's some empty text nodes, including one at the very end, which creates the extra newline (see words[7] and words[8] in the output below):

The text and options fed to richtext.create():

DEBUG:SCRIPT: "We'll be bringing in a subject. They're a trained actor, but should be fully in character for the duration. I'm to be considered invisible and inaudible by the actor, but I'll be guiding you along.<nobr> <img=t:advance/></nobr>",
