[ Upstream commit bbe246f875d064ecfb872fe4f66152e743dfd22d ]
According to the awk manual, the -e option does not need to be specified
in front of 'program' (unless you need to mix program-file).
The redundant -e option can cause error when users use awk tools other
than gawk (for example, mawk does not support the -e option).
Error Example:
awk: not an option: -e
