error in nim.cfg does not make the compiler quit with an error code

[alaviss]

Example

Use this test.nim.cfg with an empty test.nim:

--gibberish

Actual Output

$ nim c test.nim || echo got error
test.nim.cfg(1, 3) Error: Invalid command line option - gibberish

Expected Output

$ nim c test.nim || echo got error
test.nim.cfg(1, 3) Error: Invalid command line option - gibberish
got error

Possible Solution

• Write error handling code for this case:

  nimskull/compiler/nim.nim

  Lines 159 to 161 in 7e7226f

     of cliErrConfigProcessing, cliErrCommandProcessing, cliFinished: 
       # TODO: more specific handling here 
       discard "error messages reported internally"
