#511 TAP file embedded into startup; gives up w/o --file/--tape unless file w/ correct name is present in current folder

[weatherman115]

Booting Fuse without an argument for a file gives me this error:

fuse-gtk: error: couldn't open 'sprite.tap': No such file or directory
fuse-gtk: error initialising -- giving up!

This started happening after running a makefile that launched Fuse with [--tape sprite.tap] presumably one too many times. Putting a file named sprite.tap into the folder reads it as if it were passed through, and calling --tape or --file with a different file name works as normal.
