Maybe you'd be better with git ls-files if you only want just what's
in the repo. Something like:

for b in "REL8_0_0" "REL8_1_0" "REL8_2_0" "REL8_3_0" "REL8_4_0"
"REL9_0_0" "REL9_1_0" "REL9_2_0" "REL9_3_0" "REL9_4_0" "REL9_5_0"
"REL9_6_0" "REL_10_0" "REL_11_0" "REL_12_0" "REL_13_0" "REL_14_0"
"REL_15_0" "REL_16_0" "REL_17_0" "REL_18_0" "master"; do git checkout
-f $b > /dev/null 2>&1 && echo -n "$b " && git ls-files -- '*.[chyl]'
| xargs cat | wc -l; done

Careful with the git checkout "-f" though.
