Work with relative paths

getAbsolutePath() was introduced in
16635e2ce062a4ffe0ebbbfa1c4d551b0e2e2521, but it is unclear to me why.
Removing it seems to fix UX inconsistencies without introducing other
issues.

It causes non-existent relative paths to be treated differently than
non-existent absolute paths: using the former crashes the program, while
using the latter results in directories being created at the provided
paths.

Closes #825
