[Rd] Question regarding .make_numeric_version with non-character input

[Hervé Pagès]

Hi Kurt,

Is it intended that numeric_version() returns an error by default on 
non-character input in R 4.4.0? It seems that I can turn this into a 
warning by setting 
_R_CHECK_STOP_ON_INVALID_NUMERIC_VERSION_INPUTS_=false but I don't seem 
to be able to find any of this mentioned in the NEWS file.

Thanks,

H.

As far as I can understand, the current code (https://github.com/wch/r-source/blob/66b91578dfc85140968f07dd4e72d8cb8a54f4c6/src/library/base/R/version.R#L50-L56) runs the following steps in case of non-character input:

Maybe the intended code is tolower(Sys.getenv("_R_CHECK_STOP_ON_INVALID_NUMERIC_VERSION_INPUTS_")) != "false" ? Or am I missing something?
