The prevailing style seems to not have trailing whitespace, but a few lines do. This is mostly in the perlasm files, but a few C files got them after the reformat. This is the result of: find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' Then bn_prime.h was excluded since this is a generated file. Note mkerr.pl has some changes in a heredoc for some help output, but other lines there lack trailing whitespace too.
