FailureListFormatter: use exception message as reason, not spec name
Created by: paddor
For me, this improves the value of the 3rd field ("reason") when working with the Quickfix list in Vim.
Additionally, rspec --help
specifies this behavior:
-f, --format FORMATTER Choose a formatter.
[p]rogress (default - dots)
[d]ocumentation (group and example names)
[h]tml
[j]son
[f]ailures ("file:line:reason", suitable for editors integration)
