tinyformat refresher

[eddelbuettel]

It would appear that tinyformat got updated so we may want to take a look. Judging from git blame it is mostly one import followed by several surgical operations / insertions. Sounds about right to you, @kevinushey ?

[kevinushey]

Yeah, seems like the update just includes fixes / workarounds for various compilers + warnings. Should be okay to bring in, although it may not help fix the issue at #354.

[eddelbuettel]

Agree after a initial M-x ediff round. Do you want to merge it in, or should I do it?

[kevinushey]

I'll let you do the honors ;) I'm currently trying to see if I can build R with ASAN and replicate #354 locally.

[eddelbuettel]

Ahh. You are ahead of me on that front -- but I surely need your help and insights with tinyformat and stop() and that whole nexus. #354 looks weird -- tickle ASAN from a constant string? But it is a very well prepared ticket ...
