each file independently from other files. The new semantics are desired in the most of practical cases, e.g.: delete lines 5-9 from each file. Keep the previous semantics of -i under a new option, -I, which uses a single continuous address space covering all files to edit in-place -- they are too cool to just drop them. Add regression tests for -i and -I. Approved by: dds Compared with: GNU sed Discussed on: -hackers MFC after: 2 weeks
