 Thanks, in the hindsight this seems a very obvious improvement, I have no
idea why I hadn't just suggested this, but what counts is that you did it
anyhow, of course.

 I would either use the replace comment (":s") which can be easily repeated
using "&" or "g&" or indeed record a macro and apply it using "@@". I think
I'd prefer the former here, but I don't know what is simpler and if there
is no better way (FWIW I'm a bit jealous that you've already discovered
macros, I think it took me many months of working with Vim before I
realized how useful they were).
