You need to quote the arguments to echo if you want to
preserve whitespace (essentially, to avoid word splitting).
$ echo $BASH_VERSION; s='foo'; s+=' bar'; echo "s = '$s'"
5.2.32(1)-release
s = 'foo bar'
(I used +=, but that's not relevant here. The important
part is to actually quote the output. If you really want
double quotes in the output, you can do that more or less as
you have, but wrapping the whole string in them too:
$ echo $BASH_VERSION; s='foo'; s+=' bar'; echo "s = \"$s\""
5.2.32(1)-release
s = "foo bar"
Quoting is generally the way to go. There are times you can
avoid it, but when in doubt, use quotes.
