"ghc -e <invalid expression>" should return non-zero exit status
When GHC is run in expression-evaluation mode (i.e. with the "-e" flag) and the expression does not compile, GHC correctly prints an error message, but then exits with exit status 0. For example:
$ ghc -e foo
<interactive>:1:1: Not in scope: `foo'
$ echo $?
0
This is inconvenient for automated scripts that call GHC.
