I understand the reluctance from the Android point of view. However, 
printf-posix imports 69 new source files to Emacs, and these files have 
not been tested extensively with Emacs on non-Android platforms. From 
the viewpoint of non-Android Emacs platforms, it's significantly less 
disruptive if merging the Android branch does not add 69 new source 
files that will require testing on these platforms.

And even from the Android viewpoint, no matter what we do to fix the 
problem some testing needs to be done anyway, as the fix is likely to 
affect Emacs in test-relevant ways.

So I propose that we merge the master branch into feature/android (to 
get the recent fix to stop using %n) and then apply the attached 
patches. The first and third patches are the actual idea. The second 
patch (compressed to save space) is automatically generated via 
admin/merge-gnulib, and consists of deleting the 69 source files.

The idea is to get feature/android merged quickly. We can revisit the 
use of Gnulib's printf-posix module later, as needed. With luck 
printf-posix won't be needed, as Emacs historically has avoided use of 
unusual printf features (for obvious portability reasons).
