It's purely a matter of this question's answer:
"Is a veeery long list of file names supplied at the command
line, or is rsync on it's own figuring out all the names
(possibly recursing through subdirectories with gazillions of
files)?"
If you supply "*" as a file name, rsync _never ever_ will see this
little star. Instead, the shell interpreter (where you've typed your
command) will substitute it with the looong list of names. If this list
exceeds a certain size (IIRC 128KB on PeeCees), the shell interpreter
will fail to start the rsync program (since the kernel cannot copy all
the data).
If you supply "." as a _directory_ name containing thousands of files,
it'll work just fine since "." isn't expanded by the shell interpreter,
but recursively read by rsync itself.
