Subject: Re: bug#21284: 25.0.50; `completion-file-name-table' should/not use `nreverse'?

If there is/are valid reason(s) to reverse the order, then perhaps consider mentioning one or more of those reasons in a comment within `completion-file-name-table' along with a mention of bug 21284.

If there is no valid reason whatsoever to reverse the order, then perhaps consider removing `nreverse` from `completion-file-name-table`.

If the issue is "de minimus", then the bug report can be closed without further ado.
