[Emacs-diffs] master 5d1d00c: Add a new compile error regexp for Clang includes

[Philipp Stephani]

branch: master
commit 5d1d00c34123aad92cffd913152987de05c5e713
Author: Philipp Stephani <address@hidden>
Commit: Philipp Stephani <address@hidden>

    Add a new compile error regexp for Clang includes
    
    Clang uses a slight variation of GCC's include format, causing includes
    to be treated as warnings instead of informational messages.  Use a new
    regular expression instead.
    
    * lisp/progmodes/compile.el
    (compilation-error-regexp-alist-alist): New element
    `clang-include' for Clang-style "included from" lines.
    * test/lisp/progmodes/compile-tests.el
    (compile-tests--test-regexps-data): Add unit test.
