Prior to this patch, the following config led to incorrect behavior:
- link:
~/.folder/file:
path: file
create: true
relative: true
relink: true
Prior to the change, running the config the first time would result in
expected behavior. However, running the config for the second time would
result in deletion and re-creation of the link (even when the link is
correct).
This patch improves the interaction of relink and relative, taking
relative paths into account when checking the validity of existing links
in the `_delete()` method.
