Added StringContainingQuotedPath, which is used for ActionItemOther. In the process, checked every ActionItemOther for those containing filenames, and made them use quoting. Sponsored-by: Graham Spencer on Patreon

{- git FilePath library
|
|
-
|
|
- Different git commands use different types of FilePaths to refer to
|
|
- files in the repository. Some commands use paths relative to the
|
|
- top of the repository even when run in a subdirectory. Adding some
|
|
- types helps keep that straight.
