B.5.1 Preview causes all sort of strange error messages

When running preview-latex and taking a look at either log file or terminal output, lots of messages like

! Preview: Snippet 3 started.
<-><->
      
l.52 \item Sie lassen sich als Funktion $
                                         y = f(x)$ darstellen.
! Preview: Snippet 3 ended.(491520+163840x2494310).
<-><->
      
l.52 \item Sie lassen sich als Funktion $y = f(x)$
                                                   darstellen.

appear (previous versions generated messages looking even more like errors). Those are not real errors (as will be noted in the log file). Or rather, while they are really TeX error messages, they are intentional. This currently is the only reliable way to pass the information from the LaTeX run of preview-latex to its Emacs part about where the previews originated in the source text. Since they are actual errors, you will also get AUCTeX to state

after the LaTeX run in the run buffer. This merely indicates that errors were present, and errors will always be present when preview-latex is operating. There might be also real errors, so in case of doubt, look for them explicitly in either run buffer or the resulting ‘.log’ file.
