The "/brlist" page:

Show a list of branches.  With no query parameters, a sortable table
is used to show all branches.  If query parameters are present a
fixed bullet list is shown.

Query parameters:

    all         Show all branches
    closed      Show only closed branches
    open        Show only open branches
    colortest   Show all branches with automatic color

When there are no query parameters, a new-style /brlist page shows
all branches in a sortable table.  The new-style /brlist page is
preferred and is the default.
