You can use these functions to save and load your position in files.
This can make it easier to return to where you were in a file after taking a break.

Before quitting, the `sfp` function saves commands to a file to open the current files, return to the current line numbers, and set the current labels.

The `lfp` function runs the commands that you saved with the `sfp` function.

The `rf` function refreshes the buffer, restores the labels, and returns to the line number that you were on.

    # Write the line number of a label of the previous buffer on the stack.
    # usage: <getlabel <label>
    # Functions rf and sfp use this function.
