Wrapping dashes are automatically applied, so that x would transform
-x-margin.
postcssShortSpacing({ prefix: 'x' });
body {
-x-margin: 1em *;
}
/* becomes */
section {
margin-top: 1em;
margin-bottom: 1em;

The skip option defines the skip token used to ignore portions of the
shorthand.
postcssShortSpacing({ skip: '-' });
