MD038: Code span containing only spaces

[straight-shoota]

When a code span contains only spaces, I think MD038 should not apply.

CommonMark describes that case to be taken as is without chopping off leading or trailing spaces (https://spec.commonmark.org/0.31.2/#code-spans).

When there are only spaces, it's very likely that they're intentional. That premise for MD038 is to avoid unintentional whitespace.
And it's even more likely that the automatic fix is much less intentional: markdownlint --fix removes all spaces.
This results in an empty code span, which is not even a valid code span. Thus the fix definitely changes semantics.
In my opinion the fix behaviour is wrong. The rule violation maybe not as clearly wrong, but I'd suggest to exempt code spans with only spaces from MD038.
