Please don't. It's better to avoid these highly specialized solutions
and instead seek general purpose ones. For instance, utilizing the
%(if:) atom suggested elsewhere, you might add an %(iscurrentbranch)
which would allow a format like this:

    %(if:iscurrentbranch)*%(endif)

Even more generic would be an %(ifeq:x:y) conditional and a
%(currentbranch) atom:

    %(ifeq:refname:currentbranch)*%(endif)

Those are just a couple ideas. Other variations are possible and
likely preferable to the specialized %(starifcurrent).
