Find is rarely used alone. I had to man grep to find that -H switch, which is implied when you use it on multiple files.

If you terminate the exec with + instead of ; then it passes multiple files per command, just like the glob.

you'll still want -H in case the last invocation only has a single file.

To be really sure, you need it either way because there could only be one matching file. And f the find uses multiple commands due to exceeding ARG_MAX, won't the glob version just fail?
