Currently using '..' or '.' in the file path for gui blame causes it to break, because the path is passed inside the SHA:PATH spec to cat-file, which apparently does not understand such items. As a result, cat-file returns nothing, and the viewer crashes because of an "index out of range" error. This commit adds a simple function that normalizes such paths. I choose not to use [file normalize], because it uses some data from the file system, e.g. dereferences symlinks, and creates an absolute path, while blame may be used to inspect historical information that bears no relation to the current filesystem state.
