i've implemented and tested the relative message selection code
as i described it earlier. thanks to all who contributed to the
design.
if "foo" denotes a single message, then just as "foo:n" currently
selects a range of n messages from foo to the (foo+(n-1))'th
(inclusive), the new syntax "foo=n" selects the single (foo+(n-1))'th
message. so given a folder containing these messages:
3
5
7
9
then 'pick cur:3' currently selects 3, 5, and 7, and now 'pick cur=3' will
select just message 7.
for sequences, just as "seq:n" currently selects a range of messages
from the start of seq through the n'th message in seq, the new "seq=n"
selects the single n'th message of seq.
so given a sequence 'seq' containing:
3
5
7
9
then 'pick seq:3' currently selects 3, 5, and 7, and now 'pick seq=3' will
select just message 7.
negative offsets work similarly. as a convenience feature when typing
negative offsets, "foo:-n" and "foo=-n" can be entered as "foo::n" and
"foo==n" respectively.
there was no discussion after i described all this last week, so i'll
push the changes soon.
