I obviously haven't seen that suggestion, but why write a script
yourself when software exists to do that already.
Keep a copy of the original file, and then edit the file so that it
works in the way you require. Now run diff on the two files and
keep the output.
When the package is upgraded and your configuration is modified,¹
you can feed the new file and your diff file into patch, which
will merge them to produce the new configuration +with+ your edits.
Before you do any of this, read man patch to get an overview
of what patch can do for you.

Patch, of course, has the same pedigree as Perl, both being creations
of Larry Wall.
¹ If your configuration file is actually a package's conffile,
then much of the work above will be duplicated by the
installation scripts using the conffile.dpkg-{old,new,tmp}
mechanism.
