+# clang-version [-p] clang-command +# +# Prints the compiler version of `command' in a canonical 4-digit form
small nit: `command` should be `clang-command`, but its just a comment (maybe the maintainer can make that change when/if applying). The conditional at the end to see if $with_patchlevel using "x" is odd, but this is what scripts/gcc-version.sh does and this patch does work as expected.
