"""Regression tests for the Add Space surrounding-quote strip.

When users use macOS Finder's "Copy as Pathname" (Cmd+Option+C) the path
arrives wrapped in single quotes by default — e.g. `'/Users/x/Documents/foo'`.
Other shells and OS file managers do similar things with double quotes.
The Add Space input would reject these as "not a directory" because the
literal quote characters became part of the path.

This file pins the behaviour:
  - Surrounding paired quotes (single or double) are stripped before validation.
  - Only the OUTERMOST pair is removed — internal quotes survive.
  - Mismatched / unpaired quotes are preserved (path may legitimately contain one).
  - Whitespace outside the quotes is also handled.
