Probably because of the -v sorting order ... so it's - once
again - a little argument for a --null option.

Otherwise, I'd suggest something like the following to avoid
the `eval` problems:

  $ ls -1v *.pdf | xargs -d$'\n' cat

And if there are even newline characters in the file names,
then maybe this would be it:

  $ printf "%s\0" *.pdf | sort -zV | xargs -0 cat

But as already mentioned, this is not a coreutils but
rather a shell programming issue.

Have a nice day,
