* Column definition:

* [0-9]+ this is the column we are mapping to
* ["+"] an optional "+" character, which means this column is copied to
* another builtin column:
* [0-9]+ the other column we are mapping to
* [,:t?] what is the separator character
* , means its a comma
* : means its a colon
* t means its \t
* ? means we have a fixed width, with the width following:
* [0-9]+ the fixed width, followed by a space (to terminate the
* width)
