I just tried cloning llvm-www.git, and the checkout failed with
error: invalid path 'devmtg/2017-10/slides/Guelton-Challenges_when_building_an_LLVM_bitcode_Obfuscator.pdf '
I assume the trailing space in the pathname is the problem. (This is on Windows, if it makes a difference.)
After a few “git restore” commands, “git status” was down to reporting just that one file as deleted. But any attempt to commit other changes still complains about the invalid path.
Help?
