The _tc_one_of_list and _tc_once_attr functions simplfy the bash
completion task by validating each attr exist only once on the command
line.
For example, for the command line:
$ a b c d e
and the call to _tc_once_attr with "a f g", the function will suggest
"f g" as "a" existed in the command line in args 0.
Add the _from variant to those functions, which allows having the command
line option once from a specified index. In the previous example, calling
_tc_once_attr with 4 and "a f g" will suggest "a f g".
