[BUG] Pot info -E lacks generates code lacking the required quoting

[Crest]

Describe the bug
The internal helper pot info -E -p $pot generates code lacking the quoting required to assign multiple words to a single variable.

To Reproduce
Steps to reproduce the behavior:

1. Create the pot with this command: pot create -v -p test -f fbsd-update -t single -N alias -S dual -i 'em0|2001:db8::2' -i 'lo0|127.0.0.2' -b 12.1
2. Run this command: pot info -E -p test
3. See error

Expected behavior
I expected this output from pot info -E -p test:

export _POT_NAME=test
export _POT_IP=127.0.0.2
export _POT_IP_0=127.0.0.2
export _POT_NIC_0=lo0
export _POT_IP_1=2001:db8::2
export _POT_NIC_1=em0
export _POT_IP_LIST=_POT_IP_0\ _POT_IP_1
export _POT_NIC_LIST=_POT_NIC_0\ _POT_NIC_1

instead I got this output:

export _POT_NAME=test
export _POT_IP=127.0.0.2
export _POT_IP_0=127.0.0.2
export _POT_NIC_0=lo0
export _POT_IP_1=2001:db8::2
export _POT_NIC_1=em0
export _POT_IP_LIST=_POT_IP_0 _POT_IP_1
export _POT_NIC_LIST=_POT_NIC_0 _POT_NIC_1

Please note the missing \ between the list elements.

Additional context
This bug prevents hooks from working correctly for multi address pots. Multiple addresses are required for dual stack operation.
