Follow-up Comment #4, bug #28912 (project findutils):

But what does the "{}" stand for? That's the question. And There seems to
appear no documentation in xargs(1) page about it.

Compare to find(1) manual page which reads:

 [option -exec] ... The string `{}' is replaced by the
 current file name being processed everywhere it occurs
 in the arguments to the command

I'm supposing that the writer has supposed that the reader is already
familiar with the find(1) use of {}.

It would be advisable to document the "-I {}" explicitly here as well. It may
not otherwise be so straightforward to consider the token "{}" as the referred
"string".

Just hoping to see that the manual would be more verbose about the
explanation.
