Emacs keyboard macros are also often a good one-off way to do this sort 
of thing.

And if you can formulate the edits as one keyboard macro activation per 
file, then you can open a Dired showing the files to be modified, and 
launch your keyboard macro on the file under point in Dired (so the 
keyboard macro opens the file, does the edit, saves and closes the file, 
moves point to the next file in the list for you to invoke the keyboard 
macro again).
