    _______________________________________________________

Details:

The following code causes a syntax error in grub but is completely valid and
causes no problems in bash:

echo \
 test

Note the space before "test". With a file test.cfg containing the above two
lines I can run "bash test.cfg" and it will simply print "test\n" as expected
but when I run "grub-script-check test.cfg" I get the following output:

error: out of memory.
error: syntax error.
Syntax error at line 2

I ran into this bug while trying to get bvk's autoiso.cfg working for Super
GRUB2 Disk.
