Formmater replace `` into $()

[Edger]

I want to assign the dns result to dns_server by networksetup -getdnsservers Wi-Fi in the shellscript, but after I format it, the formatter replace `` into $(), show as below:

before format:

dns_server=`networksetup -getdnsservers Wi-Fi`

after format:

dns_server=$(networksetup -getdnsservers Wi-Fi)

this is upstream issue，

you can query the cause from the author.
I think $(…) is much clearer and easier to use when nesting.

Well, the problem is, after the replacement, this command can not execute correctly.

@foxundermoon could this issue please be reopened? It seems that $() and `` are not always interchangeable., and converting one to the other may break existing code.

An example:

input="ap-southeast-2c"

echo `echo $input | sed -e 's:\([0-9]\)[a-z]*\$:\\1:'` #ap-southeast-2
echo $(echo $input | sed -e 's:\([0-9]\)[a-z]*\$:\\1:') #ap-southeast-2c
