For each line, patterns are are scanned in order, and the first match
determines the outcome: If it is a negative pattern (i.e., it begins
with an exclamation mark), the line is not a hunk header; if it is a
positive pattern, the line is a hunk header. If no pattern matches, the
line is not a hunk header, either; it is as if the list were terminated
by a negative catch-all pattern.
Due to these rules, negative patterns in the list are only necessary
when you want to make an exception to a positive pattern in the list,
and then the negative pattern must be listed before the positive pattern.
In the csharp case, I do not see a pattern of which the keyword pattern
would make an exception (neither the old version nor your new version).
Therefore, you could drop the keyword pattern entirely.
