without the patch, the error isn't correct either: $ grep -P '[a]'grep: the -P option only supports a single pattern
I don't offhand see what's wrong with the diagnostic, as the PATTERNS operand is documented to be one that "contains one or more patterns separated by newlines".
doing the one that compiles every line independently and that will catch that problem wouldn't be that difficult, but I would rather do it as a follow up, and is definitely going to be bigger.
Yes, that sounds better. Please keep the followup in this thread. Also, I hope you'd be willing to assign copyright to the FSF as I assume these changes will be nontrivial. I will send you paperwork info about that via separate mail offlist.
