a few comments:
the default comparator is always "i;ascii-casemap", so it can be omitted
from the examples.
the actions and tests allows a list of flags to be specified as a space
delimited string. I assume this is intended to allow variable
references. e.g.:
set "s" "\\Answered Closed";
setflag "f" ["${s}", "\\Deleted"];
if hasflag "${f}" "${s}" ...
do we really need "setflag"? it is equivalent with "set", except it
allows some syntax checking of the arguments, but as you can see above,
it can't really do much of it statically anyhow. I think most users
will use "addflag" almost exclusively.
