Using `res-2` in output-spaces argument causes failure if a file named "2" exists in the current directory

[stilley2]

This is covered here, but I wanted to document the issue in this repo in case anybody runs into this problem. Effects release 1.4.0.

Can you provide the stack trace from fMRIPrep? (or a clearer description of how to replicate this)

[stilley2]

Unfortunately fmriprep seems to catch and disregard the stack trace somehow (I never tracked down how), but here's the end of the log. The error occurs because I have a fail named "2" in my home directory.
