blockspec is a block specifier which must point to a GTI table,
a mask image, or a region table respectively. It must
be in either of the four forms setname, setname+blockid,
setname[blockid], or setname:blockid where setname must
be the name of an existing data set and
blockid an identifier of a block in that data set.
If the first form, setname, is used, the filter data are sought in the
first block of the named data set. For the latter three forms, the
data set name is optional. If omitted, it refers to the data set of
the currently processed table. blockid can either be an identifier
starting with a letter which must then be the name of a block in the
specified data set or a simple number which is directly interpreted as a
block sequence number (starting from 1).
