Perhaps, but I do not know if wrap() is even better. The only reason I
said w() here is because I saw you used w() and this is meant to be a
superset replacement for it, as this can re-wrap anything, not just one
particular field from the commit object.

I may be missing the issue you are raising here, but it parses the string
only once; it stuffs the expansion of the enclosed string into a separate
buffer (while noting where it ends), applies the function to the result
obtained in the separate buffer and appends the result of the function
application to the main buffer, and the main expansion resumes where the
nested one finished.
