[Help-bash] Command Substitution

[Kevin Connor Arpe]

Hello,

I am seeking clarification about the Bash 4.2 man page.  I downloaded
the latest source and built a binary from scratch on Linux.

Section "Command Substitution" has the following sentence:
"If the substitution appears within double quotes, word splitting and
pathname expansion are not performed on the results."

Unless I misunderstand, this sentence is inconsistent with the following:
$ bash
$ echo $BASH_VERSION
4.2.0(2)-release
$ var="data
> more   data"
$ echo $var
data more data
$ echo "[$var]"
[data
more   data]
# ^^^ Should be '[data more data]'?
$ var2=$(echo "$var")
$ echo $var2
data more data
$ echo "[$var2]"
[data
more   data]
# ^^^ Should be '[data more data]'?
$ bash
$ var3="$(echo "$var")"
$ echo $var3
data more data
$ echo "[$var3]"
[data
more   data]

Please help to clarify.

Thanks,
Kevin Connor ARPE
