This is essentially internal function. It exists because, in general, it is not possible to restore the original Rd file from the Rd object due to the specifications of the Rd format. The file exported from the parsed Rd file is functionally equivalent to the original but equivalent things for the computer are not necessarily equally pleasant for humans.

This function is used by reprompt when the source is from a file and the option to keep the source of unchanged sections as in the original.

todo: needs clean up, there are unnecessary arguments in particular.


the main result is the side effect of replacing sections in

file not changed by reprompt with the original ones.
