bug#39999: sed -i non-POSIX

[wlharvey4]

Greg,

Good point.  The BSD sed man page says:

"The -E, -a and -i options are non-standard FreeBSD extensions and may not be available on other operating systems."

So perhaps a better solution is to not use the -i option at all and be POSIX compliant?

Informally looking through some of the code, this was the only use of the -i option that I found.
