Due to the length of my name, it's often wrapped in comments. This is entirely understandable. However, it often gets wrapped like this:
...[end of comment] -
Timothy Mueller-Harder
which looks really weird. I'm fine with
...[end of comment] -Timothy
Mueller-Harder
as well as
...[end of comment]
- Timothy Mueller-Harder
but wrapping between the hyphen and my first name is ridiculous. Please change this.
(Edit) Here's an example: 
The rendered HTML is already like you're proposing, e.g.:
– <a href="/users/12285/timothy-mueller-harder"...
so this sounds like a browser issue. Indeed, only Firefox seems to render the correctly*:
* Unless we're doing something wrong, which is entirely possible :)
If you are advocating that Stack Exchange removes the space between the end of the comment and the username, or linebreaks the dash ending the comment, I am 100% opposed to that.
This is standard browser line-wrapping behavior. When content hits the end of a displayed line, it rewinds to the last (non-breaking) space, and then moves all the content onto the next line.
You're just going to keep running into this problem.
So what can you do? My only suggestion is to change your username. The only three names I could think of that could permanently resolve this issue would be Timothy-Mueller-Harder, TMH, or TM-H. You could abbreviate it in some other fashion, such as Timothy M-H, but that won't fix the issue. You will inevitably post a comment of some length that pushes not only M-H onto the next line, but Timothy as well.
