Fix StackOverflowError during cherry-pick submit
Using a regex pattern of "^(\n|.)*\n..." causes the Java regex package
to recurse for each consideration of the first alternation, creating a
very deep stack for a relatively short commit message. If the message
is large enough, the thread stack overflows, and an exception is thrown.
Instead we use a more customized parser, to examine the message end and
determine if an LF should be appended, or not.
