Would you occasionally like to take the usage of quadrigraphs into account
(according to the application of M4 quotation)?
https://www.gnu.org/software/autoconf/manual/autoconf-2.71/html_node/Quadrigraphs.html
A parameter for the command “echo” is enclosed by double quotes so far.
Variable expansion is not applied in the passed string.
Can it be nicer then to enclose this argument by single quotes?
Regards,
Markus
