Request: Make the CTRL + backspace behavior for paths apply to more types of paths or allow plugins to customize it

[TBM13]

Currently the CTRL + backspace behavior is hardcoded to:

1. If the query is a valid path, remove everything until the last '\' that isn't at the end, e.g.:
   • C:\Asd\Some Example -> C:\Asd\
   • C:\Asd\Some Example\ -> C:\Asd\
2. Otherwise, behave normally:
   • Example\Asd\Some Example -> Example\Asd\Some
   • Example\Asd\Some Example\ -> Example\Asd\Some Example

I'd like for the behavior of the first case to apply to more types of paths since plugins like the registry's or a Windows Tasks plugin I'm making have paths such as:

• HKCU\Keyboard Layout\Preload\
• \Microsoft\Windows\AccountHealth\

These paths don't follow the format of letter + colon + slash (e.g. C:\) so they aren't considered valid paths.
