It might be a bit out of the norm, but most tools / apps I've encountered (even cmd.exe) support forward slash style absolute paths on Windows.
If this is an explicit choice a better error message than "Path isn't absolute and no reference file provided" would be helpful at least.
I've only had a cursory look at the code, so I don't know what would be the best proper way to add this, but the simplest would be to adjust the slash direction according to expectations. I suppose modifying paths is not the most expected / preferred outcome, so perhaps adding support for both directions might be better, albeit probably trickier and would double a lot of code.
