+
+removes all newlines without inserting spaces
+That usually isn’t what we want for shell lists.
+It should typically be space-separated output.
+
+Fixes a bug seen with yocto where compiler is not a single word
+but a string e.g.
+
+ccache aarch64-yoe-linux-musl-clang++  -mcpu=cortex-a72+crc+nocrypto   --dyld-prefix=/usr -fstack-protector-strong  -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/mnt/b/yoe/master/build/tmp/work/cortexa72-yoe-linux-musl/libtorrent/0.16.1/recipe-sysroot
+
+It changes it to

+ccacheaarch64-yoe-linux-musl-clang++-mcpu=cortex-a72+crc+nocrypto--dyld-prefix=/usr-fstack-protector-strong-O2-D_FORTIFY_SOURCE=2-Wformat-Wformat-security-Werror=format-security--sysroot=/mnt/b/yoe/master/build/tmp/work/cortexa72-yoe-linux-musl/libtorrent/0.16.1/recipe-sysroot
+
+When doing c++17 checks on compiler, resulting in failure
