make see tool cope with process subtitution

[monkeydom]

currently cmds like
see <(ls) - but they should not

There is no good way to support >(some command) though

proposed solution:

the see tool should treat those like a pipe in and serialize them into tmp files to give to see to open transiently

also note that
/dev/fd/0 and /dev/stdin should be treated the same as the - shortcut
