Usually I'm content to assume that lists of files and such that I'm
going to act on were produced in a way I have control over and have the
right number of words in the right place. When I need to double-check,
is there a more compact way than a huge cascade of PICK and VERIFY
stages like this?
... | pick 136 == " "
| pick substr w1 of 137.8 ¬== ""
| pick substr w2 of 137.8 == ""
| pick 145 == " "
| pick substr w1 of 146.8 ¬== ""
| pick substr w2 of 146.8 == ""
| pick 154 == " "
| pick substr w1 of 155.2 ¬== ""
| pick substr w2 of 155.2 == ""
| verify 157 " "
| ...
¬R
