   Mprof is unable to parse white space, therefore blank lines need to be deleted.

   This is weird, could you please post a sample program so we can reproduce the issue?

   @astrojuanlu The problem occurs when mprof run <command> has multi-line arguments:

   For example:

   read -r -d '' MESSAGE << EOM            
     hello
     world
   EOM
   
   mprof run echo "$MESSAGE"
   mprof plot

   Using last profile data.
