Disable markdown formatting in showInformationMessage by default

[hatroman]

I've found an open issue (#6087) about markdown in show*Message. And I assume that this functionality is not implemented yet. But if I try to show message with __(double underscore), for example abc__def, underscore characters will be lost and the rest of the text will be italic. I have not found how to disable this type of formatting

• VSCode Version: 1.9.1
• OS Version: macOS Sierra 10.12.3

Steps to Reproduce:

1. just try window.showInformationMessage('abc__def');
2. and you'll get abcdef, but def in italic

I was not aware we support markdown in the message API.

this is the message service: https://github.com/Microsoft/vscode/blob/master/src/vs/workbench/services/message/browser/messageList.ts#L274

@hatroman we support a subset of formatting for messages, not full markdown:

• * to turn into bold
• _ to turn into italics
• [ and ] to mark links inside the message

You can prefix with \\ to escape.

it would be better if i could choose. Sometimes I have calculated value for message and don't now what kind of symbols it contains. Now I will have to escape every time each message. 😞

That would require new API for extensions and the default cannot be that we disable this formatting, otherwise we break existing extensions.

👌 thanks anyway

re #20595 (comment) - we should measure how often that actually happens. We never really documented this and the deal is then that we try to see how is using it, inform them, and change it.
