You can insert *any* commands in the ghci file. including some system
commands, to delete everything.
That's probably the reason to deny a file to be group writable (anyone
in a group could write bad thing in there)
you can try putting the following in the .ghci to check for example:
readFile "somefileyouwanttoread" >>= writeFile "/tmp/apublicplace"
