Hi,
The new function is similar to "rename-file", but it automatically opens
the file once it's renamed (or throws a relevant error).
I'm not sure if this addition is necessary, but I've had it for so many
years that I thought it might be useful to have it in Emacs by
default. I'm also not sure if it's in the correct position within
lisp/files.el. In any case, I'm submitting this patch for consideration.

Subject: [PATCH] Add rename-file-and-open function
Introduce rename-file-and-open, a new function that renames a file and
opens the renamed file immediately. This function was developed to
make the renaming of a file more automated: when using rename-file, the
renamed file is not automatically opened, requiring an additional
step to open it manually.
The rename-file-and-open function takes two required arguments:
- file: the source file name (a string)
- newname: the destination file name (a string)
- ok-if-already-exists: control the behavior when the destination
file already exists
It calls rename-file to perform the actual renaming, handling any
file-error that may occur by signaling a user-error with an appropriate
error message.
* lisp/files.el (rename-file-and-open): New function to rename a file
and open it, since `rename-file' doesn't open the renamed file.
