[Bug-AUCTeX] 11.82; preview-latex incompatible with e-TeX's "-file-line-error" option

[Markus Ueberall]

Hi there,

when using e-TeX's "-file-line-error" option, preview-latex is unable
to parse/detect the resulting 'error' messages.
(This seems to be the very reason why the current teTeX 3.0 release
for, e.g., Cygwin -- which uses pdfeTeX with the forementioned option by
default -- prevents the display of preview images.)

Though a temporary solution would be to simply turn off the
"file:line:error style" (e.g., by adding "-no-file-line-error" when invoking
e-TeX), it'd be preferable to allow for this style as well...

Below is an excerpt from the output of the enclosed sample file "circ.tex":
