In Ex mode, any error message causes to set exit code non-zero.
According to source code comment, this is for POSIX compliant.
To exit with 0, use :visual command before :quit.

main.c:getout()
/* When running in Ex mode an error causes us to exit with a non-zero exit
* code. POSIX requires this, although it's not 100% clear from the
* standard. */
if (exmode_active)
exitval += ex_exitval;
