Widespread, yes.

Well, there is two cases: - You are doing this just once or twice: then it does not make much sense to create scripts or use tools; but then it is not too much of an issue to copy & paste line by line either. - You are doing this more frequently. Then copy & paste is a cumbersome and error prone procedure. You have to be careful about quoting etc., and errors are not easy to detect. In such a situation it always makes sense to think about more efficient ways: 1) Use tools. For example, use something like "expect" or similar to send your inout line by line, always waiting for the next command prompt. 2) Use a U-Boot script image which you can download and run. 3) Use a plain text file which you can "env import". 4) ... > > In the special case of setting environment variables, consider using > > featurs like "env import" instead. > > s/and run it/and "env import" it/ No. Running a script image is one solution; using "env import" is another, independent one. > > Multi-line input has never been supported. > > Hence this patch, I feel.

But your patch does not _solve_ the problem. It just extends the limits a bit - to som degree that seems to be acceptable to you, but the next person might paste a few lines more, and it's failing again. I think it's much better to state clearly that multi-line input is not supported than to claim it is, without being able to give a precise limit where it will fail, or without being able to detect error situations clearly.
