Re: backslash whitespace newline
For what it's worth, my opinion:
A program whose semantics depends on invisible end-of-line
whitespace is erroneous and a disaster waiting to happen.
The portability argument wrt other compilers is all very
well, but the code fails to be portable in so many other
ways, as people have mentioned: cut-and-paste; web archives;
reading printed-out code; not to mention virtual 80-column
punch cards on VM/CMS ...
I'd like to keep the current behavior, but add a warning,
which should default to on.
I'll go along with a compromise: change the behavior to
match the "other compilers", as along as a warning is
emitted. The warning can be turned off with our generic
turn-off-specific-warnings framework (I'm so out of gcc
development I'm not sure we have one - but I vaguely
remember reading about it). However, the warning should be
on by default.
