If you're not comfortable with sed, you can always create a patch
using 'diff -u foo1 bar2 > foo-bar.patch' and add to source=() ... But
since we are here:

My sed command executes an expression in an input text. The input text
is from the file 'lmd'. I also added the flag '-i' so the output of
this command will not go to stdout, but directly to the input file.
So, it will not just read the file, but alter/write too.

The expression structure is basically 'A#B#C#', where #s are
delimiters; A is a specific line number that sed will look and
replace; B is the regexp to look (and to be replaced) in that line in
A; and C is the replacement regexp that I want to replace B. Please
note that '\n' is a newline character and '\t' is a tab character.

So, as I mentioned before, I replaced the string 'then' in line 325
with the new line/command you provided.

'sed' can do much more than that. Man page and google can help a lot.
