Subject: bug#33824: coreutils v.8.30 – An expression part of a cat command is interpreted as "ambiguous redirect" when applied to a target.

Component: coreutils.x86_64  8.30. Observation not reported at pixelbeat.org
<https://www.pixelbeat.org/docs/coreutils-gotchas.html>.

Command executed:
$ cat a* >> b*
bash: b*: ambiguous redirect

Thought the same syntax is used with success when applied only to source
files:
$ cat a* >> b
$

Probably a bug. Regards, R.T.
