short-format appears to be additive not replacing (as expected)

[FrankMittelbach]

From the documentation (as well as from earlier behavior) I would have expected that one can set a default with \acsetup and overwrite that on the individual acronym, but it is seem that both get applied:

\documentclass{article}

\usepackage{acro}
\acsetup{short-format=\textbf}

\DeclareAcronym{cd}{short=CD, long=Compact Disc}
\DeclareAcronym{etc}{short = etc.\@, long=et cetera,
                     short-format=\textit, first-style=short}

\begin{document}
\ac{cd}             \\
\ac{etc} --- short format overwrite not honored
\end{document}

This is actually mentioned in the manual (p.19):

Per default the individual formatting instructions are additive to the global ones. This can be changed through the option format/replace = true|false (Initial: false)

[FrankMittelbach]

hmm yes :-) has this changed recently (in the last year or so) or have I never noticed that when I made the examples originally?

[cgnieder]

It has changed with the upgrade to v3. I am wondering if the original behavior should be the default, though…

[FrankMittelbach]

difficult to say, but if you look around what other packages do then this behavior as a default is fairly unique and normally you can expect that local changes overwrite and not add to the default. would be good for me to know if you alter the default because that affects a lot of the explanation how things work.

[cgnieder]

Yes, I decided to revert to the old behavior. It seems to be the more intuitive alternative. I'll update acro this weekend with the new (old) behavior and the bug fixes.
