Date: Sat, 26 Mar 2016 21:36:31 +0000

branch: externals/auctex
commit f91946802bd0bc6689de31493da9d8f8e55abfbb
Author: Tassilo Horn <address@hidden>
Commit: Tassilo Horn <address@hidden>

    Improve TeX error parsing.
    
    * tex-buf.el (TeX-error): Error if file containing the TeX error
    doesn't exist instead of finding a new file.
    (TeX-parse-error): Greatly simplify the new file and end of file
    regexps.
