bug#21284: 25.0.50; `completion-file-name-table' should/not use `nrevers


From: Keith David Bershatsky
Subject: bug#21284: 25.0.50; `completion-file-name-table' should/not use `nreverse'?
Date: Mon, 17 Aug 2015 10:25:13 -0700

The function `completion-file-name-table' uses `(setq all (nreverse comp))' 
instead of `(setq all comp)'.

This has the effect of reversing what was accomplished when 
`pcomplete-compare-entry-function' is set to `'string-lessp'.

In a nutshell, the completions are in reverse alphabetical order as a result of 
`(setq all (nreverse comp))'.

This was tested in an eshell buffer by typing at a prompt:  rm [space tab]; 
and, with `lawlist-eshell-cmpl-compare-entry-function` set to `'string-lessp'.

Thanks,

Keith
