Improve message-web text format

[therealryan]

message-web's treatment of multiline values leaves a little something to be desired - it's good that it indents them, but in the result (for example) it's difficult to spot where the padding ends and the content begins.

We should improve the output to make it more obvious (perhaps?).

Hi, you are right. I will have a look into this. Also this is my first issue so I am kinda excited to help :D

Cheers

[Arian-Ott]

Btw, what output do you exactly suggest?

[therealryan]

I think it'd probably be enough to put │ characters at the right-hand side of the padding. That should make it more obvious where the content begins

[therealryan]

If you were feeling especially fancy, you could put a └ on the last line of multiline content to make the distinction from the next value clearer

[therealryan]

Give me a shout if you need any help getting the project set up and building. As you won't be changing the angular app you can avoid having to install node if you want (just build with, e.g.: mvn test -Dnode=none.
This test will show the impact of your changes.

I'm new doing contributions to open-source projects and I think this could be a good first task, can you assign this to me?
