Is it forgotten?

Just use `echo $1 | tr ' ' '\n' | sort | tr '\n' ' '` directly and
remove the local variable.

IMHO, this function is not really usefull. We could rafactorize this later
if the setup is more complicated than `=()`.

Plus, I think you should not use this kind of global variable but simply
use a "entries" local var in the different functions then append the
sorted version. I recommend you to use a simple string variable. You'll
feel it easier to sort. COMPREPLY still need to be an array ofc cause of
bash .. ^^

Give this method the tmp_compreply words variable as first argument.

Something as:

```diff
- _append_tmp_compreply () {
-     # sort the TMP_COMPREPLY array
-     IFS=$'\n' TMP_COMPREPLY=($(sort <<<"${TMP_COMPREPLY[*]}")); unset IFS
-     # append the tmp array to the COMPREPLY
-     COMPREPLY+=( "${TMP_COMPREPLY[@]}" )
- }
+ _append_to_compreply () {
+     for word in "$(_sort_entries_string "$1")"; do
+         COMPREPLY+="$word"
+     done
+ }
```

This example shows you that commentaries are not mandatory if the code
is simple!

Plus, be carreful to use the good indentation way. In this script, we use
tabulation instead of spaces.

This changes got impact in the 3 differents `_pass_complete_blabla`
methods. I let you to find the better way to change them.
