#565 cat misses 8192nd arugment character

[Jeff]

I'm calling cat in a make recipe:
cat $(ARGUMENTS) or cat $(subst \,/,$(ARGUMENTS) )
Outputs error: "cat: pah/to/somefile.txt No such file or directory"
The argument given was: path/to/somefile.txt
The missing 't' is character 8192 on the command line AFTER the executable
Calling as: cat $(ARGUMENTS) or cat.exe $(ARGUMENTS) does not change which argument character is dropped.

Note tested with cat --version:
cat (GNU coreutils) 5.3.0
cat (GNU coreutils) 5.97
cat (GNU textutils) 2.0
cat (GNU coreutils) 8.25 Packaged by Cygwin (8.25-3)

Also note: calling tar -cvf had no errors.
