commit 091aa93d0f4cc8c1af342e8711e87e8596d0d35a
Author: Alexandre Oliva <oliva@adacore.com>
Date:   Tue Jul 7 09:02:01 2020 +0200

    accept <case> and [cond] in ChangeLog
    
    Only '(' and ':' currently terminate file lists in ChangeLog entries
    in the ChangeLog parser.  This rules out such legitimate entries as:
    
    * filename <CASE>:
    * filename [COND]:
    
    This patch extends the ChangeLog parser to recognize these forms.
    
    for  contrib/ChangeLog
    
            * gcc-changelog/git_commit.py: Support CASE and COND.
            * gcc-changelog/test_patches.txt: Add test.
            * gcc-changelog/test_email.py: Add test.
