I envy you for the blessing of such a clean C++ source that you do not
have any, say, Unix shell script in it. Try this, and weep:

	$ printf 'echo \\\r\n\t123\r\n' >a1

	$ sh a1

	a1: 2: a1: 123: not found

For the same reason (Unix shell not handling CR/LF gracefull), I went
through that painful work that finally landed as 00ddc9d13ca (Fix build
with core.autocrlf=true, 2017-05-09).
