Rewrite patterns#

1. nonstar\absolutevalue{#1}\abs{#1}
2. star\absolutevalue*{#1}\abs*{#1}

Examples#

Each example shows this rule applied in isolation. A complete normalization profile may make additional changes.

\absolutevalue{z}^2=x^2+y^2

\abs{z}^2=x^2+y^2

\absolutevalue*{z}^2=x^2+y^2

\abs*{z}^2=x^2+y^2

Notes#

This alias preserves the star marker; fixed-size fence expansion belongs to abs-to-vert-fence.
