The issue you have there is mainly that the quotes are serving double
purpose. Yes, they delimit and thus can be used to surround a file
name with spaces in it, but they're also significant to a couple of
apps (FIND uses them to indicate the search string, START looks for a
quoted argument to use as the title). I'm not entirely sure how it's
done under the covers; C code looking at argc/argv sees quoted
arguments without their quotes, exactly as I would expect on Unix, and
yet the convention is to notice the quotes.

The issue with START is 100% understandable and 100% annoying.
