If it
expands to more than one word, bash reports an error.
It seems to leave off variable expansion.
I don't understand this... either it should be reporting an error, or
it should *not* be expanding the variable. It doesn't seem to report
an error on multiple-file pathname expansions either:
imadev:~$ read a <<< *.pdf
imadev:~$ echo "$a"
*.pdf
In fact, it's not even performing the expansion, as far as I can tell.
The quoted paragraph applies to all redirection operators (and parameter
and variable expansion are still identical). The description of <<<
notes that it does not perform pathname expansion at all.

Um...the description from "<<<", above indicates it is...subject to
pathname expansion...If I had matching filesin my dir, it expanded and
returned them,
so I'm pretty sure it does PN expansion.
