The issue is that I often use the re-indent command on code that I haven't
written myself, to make it more readable. (It is amazing to me how some
people manage to get any work done on totally badly indented XML files!) So
I don't have the option of putting the /> on a new line.

As a workaround, I changed decreaseIndentPattern to kick in when it finds a
/> on a line where there is no corresponding <. So you would get the
following:

<foo>
    <bar
        a1="v1"
        a2="v2"
    a3="v3"/>
    <bar/>
</foo>

The a3="v3" is not properly aligned with the a2="v2", but at least the
remainder of the code around is properly indented. With this updated
decreaseIndentPattern, if you put the /> on a new line, as you suggested,
you also get the correct indentation:

<foo>
    <bar
        a1="v1"
        a2="v2"
        a3="v3"
    />
    <bar/>
</foo>

Not ideal, but I think an improvement over the default pattern. Here is the
updated pattern:

decreaseIndentPattern = '^\s*(</[^>]+>|-->|--%>|[^<]*/>)';
