Bug #13858: getoptlong cannot process multiple line argument with equal sign (=) version

Here is the test case:

more getopt.rb

require 'getoptlong'

a=GetoptLong.new(
[ '--user', '-u', GetoptLong::REQUIRED_ARGUMENT ],
[ '--statement', '-s', GetoptLong::REQUIRED_ARGUMENT ],
)

a.each { |x, y|
p x
p y
}

Here is the problem:

ruby getopt.rb --user me --statement="

select now() from dual
"

"--user"
"me"
"--statement"
""

Please note the statement is empty while it is not. On contrary, without "=" sign it works fine:

ruby getopt.rb --user me --statement "

select now() from dual
"

"--user"
"me"
"--statement"
"\nselect now() from dual\n"

It is believed this bug is due to the regex that GetoptLong uses to parse the argument for long opts. Please investigate and fix, thanks!
