reexports.Rd re-writes lubridate functions re-exported

[jeffcraggy]

Creating a package with usethis::create_package(), roxygen2 v 7.3.0,

Adding re-exported functions from lubridate in the /R/lubridate.R file:

  #' @export
  #' @importFrom lubridate %m+%
  lubridate::`%m+%`

  #' @export
  #' @importFrom lubridate %m-%
  lubridate::`%m-%`

As shown here: 11.8.2 Re-exporting

The first two times the package is documented devtools::document(), when reexports.Rd is created, it will switch %m+% to %m-% and vice verse.
However, if the package is documented a third time, there is no change, but if the package is checked - devtools::check(), (which writes reexport.Rd again), the bug re-appears and the functions operators switch places in the man pages doc.

Note that the reexports.Rd contents \alias{%m+%} never changes, nor the \link to the function, only the actual symbol changes from + to - and - to +.

Contents reexports.Rd :

% Generated by roxygen2: do not edit by hand

\docType{import}
\name{reexports}
\alias{reexports}
\alias{\%m+\%}
\alias{\%m-\%}

\describe{

}}`

\describe{
  \item{lubridate}{\code{\link[lubridate:mplus]{\%m+\%}}, \code{\link[lubridate:mplus]{\%m-\%}}}
}}

After further investigation, it appears that lubridate calls both functions mplus. So perhaps this is a bug with lubridate and not roxygen2?

Oh you know what, I see that %m-%is an alias of%m+% so they are not one-to-one operations.

Perhaps I should only be re-exporting %m+% and omit %m-%?
