[Bug-AUCTeX] 11.87; TeX-parse-error problems

TeX-parse-error() has problems with certain comment lines. Examples are
  Package hyperref Message: Driver (autodetected): hpdftex.
from the hyperref package. In the first case the opening parenthesis is not recognized as the start of a file because of the non-space ":" after the closing parenthesis, but the closing parenthesis is seen as the end of a file.

Adding the same restriction "\\(?: \\|\r?$\\)" to the end of the "End of file" detection solves the problem for the above example. However, it creates problems for other comment lines, such as
  [Loading MPS to PDF converter (version 2006.09.02).]
from context/base/supp-pdf.mkii.

For the moment, I applied the following patch, which seems to solve my problems.

Best regards,

Luc Van Eycken
