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.
