Strings with multiple whitespaces are formatted with single one #1026
Description
Formatting this XML:
<Tag><Inner>Test Spaces</Inner></Tag>leads to this:
<Tag>
<Inner>Test Spaces</Inner>
</Tag>I am aware of #1017, and setting "files.trimTrailingWhitespace":false does not solve the problem. All multiple whitespaces are always formatted as single whitespce:
<Tag><Inner> Test Spaces </Inner></Tag>becomes:
<Tag>
<Inner> Test Spaces </Inner>
</Tag>

Ok, I see that there is an option where you can specify tag names for which to preserve spaces.
Adding tag <Inner> in my case, does fix the problem.
I think that manually adding tag names to a list is not an viable and scalable way to handle that.
Probably, it would be better to add an option checkbox that sets the default handling for multiple whitespaces: when checked, it should preveserve whitespaces for all tags. And the tagnames list, maybe, should be turned in a blacklist for tags that need whitespaces trimmed.
Also, using the legacy formatter preserves spaces as well.
