Treat numerical digits as new 'words' in fuzzy search

When locating files or classes whose names consist of multiple words (or auto-completing code), you can type the initial letter of each word. This generally works well. However, I think it behaves unintuitively if the name contains digits: It treats the digits as a continuation of a word, rather than as a new 'word'.

For example, given the name, "Fancy4PartThingy", I would intuitively abbreviate it to "F4PT", but if you type that into the locator, it won't find it: you have to type "FPT" instead, which then shows you the Fancy3PartThingy and Fancy5PartThingy as well.

If digits were treated as new 'words', the way capital letters are, I think it would be more intuitive.
