Except that a text file shouldn't have a mixture of LFs and CRLFs.
I'd prefer to keep treating that as an error, as is done today.
Here's my reasoning, using a copy of curl.html that I have laying around as
The file is 87,203 bytes with 689 LFs so most servers will report a SIZE of
We receive 87,892 bytes once the LFs become CRLFs and this is one of the two
possible lengths that will make us happy (those being 87,203 or 87,892).
But allowing for a mixture means that we'd treat anything from 87,203
through 87,892 as OK.
So the chances of us mistaking a bad transfer as good goes way up.
I don't think it's worth it to accommodate text files with bad line endings.
