Thanks for doing that. I read through those issues, and the only one that seems 
relevant (i.e., resolved by austingroup but not in Gnulib) is the business with 
the + conversion specification flag. I installed this Gnulib patch to implement 
the flag:

https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=188d87b05190690d6f8b0577ec65ef221a711d08

Then I installed the attached coreutils patches to propagate the Gnulib patch 
into coreutils, and I am marking this coreutils bug as done.

glibc strftime should also support the + conversion specification flag. I filed 
a bug report for that here:
