I wouldn't go about planning on circumventing the emote structure on purpose. However, just working with your example -- and imagining it being typed real-time -- reveals why it's actually more fluid to create and combine short emotes and says than to try and put everything on one line. Here's what other players would "perceive" with a typical 80 character width, assuming you type roughly 45 words per minute:

A russet male centaur readies his bow, his movements careful and steady as he places his attention
fully on his prey. "You shan't escape from me *this* time," he whispers lightly under his
breath, a small smile spreading across his face in anticipation.

etc., etc.
To be honest, that one emote meets the description requirement of the MUD... and my MUD eyes aren't trained to read text from other players in such a large group. That, and I don't even really get the chance to, because the combat spam takes over.
On the other hand:

Even though it generates a little more spam, especially if you're typing on the fly, this actually comes out more fluidly, and is far more entertaining for the reader than almost a full minute of silence followed by a paragraph-long emote.
