macOS awk: brewer.awk generation error: too many open files
I thought I fixed this bug a few months ago, but I didn't, I broke the code. Filing an issue to track the original bug, the fix, and the rollback-proper-fix.
$ make
...
awk -f brewer.awk ../../lib/common/brewer_colors
awk: colortmp/brbg7 makes too many open files
input record number 131, file ../../lib/common/brewer_colors
source line number 13
make: *** [colors.html] Error 2
