Seems that folk are having issues with uploading 0-byte files from
Windows agents. This effectively removes the support for Windows for
uploading from named files that, due to `isFIFO` returning `false` on
Windows for named pipes created using MSYS2's `mkfifo` command, resorted
to checking if the file size is 0 - a common trait of named pipes.
