Bash at least says:  pencil pen{cil}

The historical context of this exception is that to avoid problems with the
find {} marker (which I believe predates shell brace expansion), and
standalone braces, it simply avoids expanding cases where brace expansion is
obviously pointless.

I believe (it's been a _long_ time), the original csh (which first
implemented brace expansion) used the same rules bash does.
