binfile is just short for binary file... it means that the file is written
exactly as presented. If you use encode (UTF8/16 etc) then you need to use
it anyway.
The PR is a pretty much single constant update (changes CR to LF for Mac
line ending).
The backwards compatibility issue is a very minor edge case. To be
impacted you need to export text from LiveCode which uses CR where a
non-LiveCode app/process consumes the data and requires the CR line
ending. LiveCode file in/out will automatically convert, so there would be
no impact to a LiveCode generated application that uses file for in/out.
