t7800: avoid arithmetic expansion notation
The construct "var=$(( something ..." is interpreted by some shells as arithmetic expansion, even when it clearly is not, e.g. var=$((foo; bar) | baz) Avoid the issue by giving an extra SP to help the parser, i.e. var=$( (foo; bar) | baz ) Noticed by Michael J Gruber.
