Bug#1063518: console-setup: setupcon: 1386: Syntax error: Missing '))'

[Sven Joachim <svenjoac@gmx.de>]

Package: console-setup
Version: 1.225
Severity: grave

After the upgrade from 1.223, console-setup.service failed to start due
to a syntax error in the setupcon script:

,----
| $ setupcon
| /usr/bin/setupcon: 1386: Syntax error: Missing '))'
`----

It looks like dash does not like the construct in line 907 where there
is an opening '$((' but the closing parentheses are split.

,----
| $ dash << 'EOF'
| > echo $((true))
| > echo $((true) )
| > EOF
| 0
| dash: 3: Syntax error: Missing '))'
| $
`----
