Using '=' to choose arguments breaks multi-line inputs for type 'string'

[thmsdmmrtn]

My code needs to input multi-line strings as a single value.
Entirety of the test code I created to test this issue:

require 'optimist'
opts = Optimist::options do
  opt :foo, 'foobar', short:none, type: :string
end
puts "foo is #{opts[:foo]}"

Command that works:

ruby rubyfile.rb --foo "bar
baz
qux" 

Output of command that works:

foo is bar
baz
qux

Command that produces error:

ruby rubyfile.rb --foo="bar
baz
qux" 

Output of command that produces error:

foo is bar

I was able to fix this by changing this line

-      when /^--(\S+?)=(.*)$/ # long argument with equals
+      when /^--(\S+)=([\s\S]*)/ # long argument with equals

It looks like the . in .* doesn't consider newlines. There's probably a better way... because regex.

The original regex is weird anyway. Not sure why it would consume from the = to the end of line?
