cvs commit: perlfaq perlfaq7.pod

cvsuser     05/03/26 23:19:01

  Modified:    .        perlfaq7.pod
  Log:
  * Do I always/never have to quote my strings or use semicolons and
  commas?
  
     + the examples are more closely related to single quoting since
     interpolation doesn't happen in these instances.
  
  * What does "bad interpreter" mean?
  
     + added note that this warning may come from line-end problems
