Before, contacting to Chet Ramey, I'd like to have some discussions.

1. How do you think rename readarray to readfile?
  
   I think the shell script writer may be confused read -a and readarray.
   readfile is more specific name.
  
2. I think it is better to make readarray options are similar to read.

   char *readarray_doc[] = {
	"Copy the lines from the input file into an array variable.",
	"Use the `-n' option to specify a count of the number of lines to copy.",
	"If -n is missing all lines are copied.",
	"Use the `-O' option to specify an index orgin to start the array.",
	"If -O is missing the origin will be 0.",
	"Use -t to chop trailing newlines (\\n) from lines.",
	"To read from stdin use '-' as the filename.",
   In stead of specifying filename, how do you think fd like 
    "read -u fd"? You can slow away `-'.

3. Do you think callback is needed?

   readarray is fast enough, so I think callback arguments is
   overkilling. I tried more than 10000 lines configure. However,
   it takes no time to read.
