commandline: display desc/epilog verbatim by default
commandline: display desc/epilog verbatim by default

It's much more common for us to want the description/epilog to be shown
verbatim to the user rather than have the newlines collapsed (I can't
find any code that wants this behavior in tree).  Set it as the default
to simplify things.

BUG=None
TEST=looked at help output of pushimage/cros_generate_breakpad_symbols/upload_symbols
