Nit: this comment predates the change. It already said 72 even though the padding goes to whatever the limit is (e.g. 132 with `-ffixed-line-length=132`), and now it also doesn't cover the no-limit case, where nothing is padded. Maybe something like:

```suggestion
// In fixed form with a column limit, source card images must be processed as
// if they were at least that many columns wide, at least in character literal
// contexts. With no limit (-ffixed-line-length=none), no padding is done,
// which matches gfortran.
```
