Your comments are fair, but in common use cases appropriate quoting of the shell command line is sufficient, especially if one can control the contents of the password and filename. If these come from arbitrary user input, then your approach is more reasonable.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —

    [moritz]: wow, that's their idea of an "improved error message"
    [moritz]: how about "This network is too large to enumerate all host addresses." or so?
    [vrk]: Well, there's a call to notcontiguous() before the error, whose description is "counts the bit positions remaining in the mask when the rightmost '0's are removed"
    [vrk]: Clear as mud!
