Removed the useless `.R` macros
Removed the useless `.R` macros

If you do `man fzf > /dev/null`, you'll get the following output

`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.

Removing these `.R` macros with a newline seems to have no effect on the
page but gets rid of the error.
