Content
After a bit of thought, I realised I could use the string.Formatter API to implement a custom formatter for the shell command helpers that auto-escapes whitespace while leaving the other shell metacharacters alone (so you can still interpolate paths containing wildcards, etc). People that want to bypass the autoescaping of whitespace can do the interpolation prior to the shell call, those that also want to escape shell metacharacters can use shlex.quote explicitly.
