[PATCH] Avoid false positives in label detection in cpp diff hunk header regex.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A C++ method start such as

        void
        foo::bar()

wasn't recognized by cpp diff driver as it mistakenly included "foo::bar" as a
label. However the colon in a label can't be followed by another colon, so
recognize this case specially to correctly detect C++ methods using this style.
