fix: line wrapping for examples without desc

[maxrimue]

This PR fixes #697. Now, if an example is defined without a description, the usage example will take up the entire line instead of just 50% of it.

looking good to me 👍 thanks for taking this on.

I think rather than having no wrap here, you should use theWrap; this way the example will still wrap onto multiple lines at the width boundary, but will take up a full line.

[maxrimue]

@bcoe So you mean I should add a width property like in line 276? 😄

[bcoe]

@maxrimue I think you want width: maxWidth(theWrap) + 4.

[maxrimue]

@bcoe I've looked at this again but it seems that even without the width property it takes up the full line:

Isn't that what you meant with but it will take up a full line?
Using the width property like you suggested makes it wrap after each character:

Anyway, what I besides would suggest is perhaps adding a newline after each example to make it more distinguishable:

This can be achieved very easily with a bottom padding of 1.

[bcoe]

@maxrimue my bad, we only need to specify width in a multi-column layout I believe.
