Very clever.
I found something like this works fine:
sed -e "1s/Ip A0/I\? A0/"
Rather than using a global edit, I told it only to change the first line
("1s"). According to my tests, sed seems to respect line numbers for
edits. Limiting sed to the first line seems safer than doing a glob

see there is an "--in-place" option for sed. I guess I better delve
into sed some more. I wonder if I can tell it to stop after the first
"\n" to avoid
