I was not around when this was posted and discussed; Shawn's note says
this is waiting for "some sort of response from Pasky", hence this request
for review and ack. It still is parked in 'pu'.

Make processing format string in custom links in action bar ('actions'
feature) more robust. Now there would be no problems if one of
expanded values (for example project name, of project filename)
contains '%'; additionally format string supports '%' escaping by
doubling, i.e. '%%' expands to '%'.
