As in Emacs. Yasnippet remove newline at end of pattern?

Question

emacs

Emacs 24.3. Yasnippet installed from melpa.
After autotyping the template, it adds a newline (adds a string). It messes up the formatting of the code. Who faced the problem? How to win?

Answer 1

The question is removed. There was some kind of glitch and it was not possible to reproduce it. =(
