| Andrew Geissler | 9aee500 | 2022-03-30 16:27:02 +0000 | [diff] [blame^] | 1 | Let us override the hashbang directly (possibly upstreamable), and don't |
| 2 | play games with hashbangs: for now assume that even hashbangs with spaces |
| 3 | are simple (assume the spaces are only used to separate arguments) and |
| 4 | we don't have long hashbangs. |
