Hi.

I am editing a simple text with actually no errors. Compilation reports
errors (what is annoying) but TeX-next-error says "No more errors."

MWE:

\documentclass{article}
\begin{document}
Bla :123:
blablabla-blablabla blablabla-blablabla
blablabla-blablabla blablabla-blablabla.
\end{document}

Investigating, in tex-buf.el one reads:

  (if (re-search-forward "^\\(!\\|.*:[0-9]+:\\) " nil t)
      (progn
        (message "%s errors in `%s'. Use %s to display." name (buffer-name)
                 (substitute-command-keys
                  "\\<TeX-mode-map>\\[TeX-next-error]"))

so error message can be triggered as easily as if input has a string like
":0: " that can go to log if that line has a bad break, like in MWE.
