Are you raising the issue with WG14 in Kona this week? I'd be wary of this sort of extension without positive views from WG14 / WG21. This patch is, in any case, missing sufficient testcases and documentation. Testcases need to include lots of variations that make clear whether the \, must appear literally like that without whitespace, or whether there might be space between them, or they might come from expansions of separate macros, etc.; formatting of the patch also appears messed up. Testcases also need to include cases that are valid with and without the option but with different semantics, to make clear that the option and its absence do the right thing in such cases. Documentation should include precise proposed standard wording to make such semantic issues clear; that's the level at which this would need to be defined. -- Joseph S. Myers jos...@codesourcery.com
