It is because the string
a{b,c}
is outside of the quotes. So the brace expansion comes first and
duplicates
the arguments to the echo call.
Yes, as you said the brace expansion is outside the double quotes so
shouldn't it

Quote them, and they do expand:

Brace expansion is essentially separate from the rest of the expansions:
in fact, it's designed to be part of a separate library if desired. As
such, it doesn't implement all of the

Brace expansion happens before parameter expansion (man bash,

Brace expansion doesn't come into play here, because the braces

The first '}' is interpreted as the end of the parameter expansion.

Brace expansion happens before parameter expansion (man bash,
EXPANSION). So the first } ends the parameter expression, and the
second } isn't special. The result of parameter

Yes. That is inconsistent with csh.

It is related to brace expansion but seems like a different case than

It looks okey, I think.
Except that b{d,e} expands to 'bd be', not 'bd,be'.
