Minor tweaks to perl-Sort-Versions in EL-4 branch

[Stepan Kasal]

Hello Paul,

thanks for your mail.  I expanded on the points you touched:

>  * Get rid of rpmlint complaint about mixed spaces and tabs

Yes, and I noticed the BuildRoot line is suboptimal: I like the
mktemp version more.

>  * Change encoding of Changes and Versions.pm (and its manpage)
>    from ISO-8859-1 to UTF-8

That's usually done by an iconv command in %prep; it's more clear
expression of the intent.

>  * Make "-depth" the first option in the find command it's used in

Correct.
While I was there, I deployed -empty and combined the two find commands
to one.  (Another option would be to use "|xargs rm -f" for the files
and then remove the empty dirs.)

Agreed, thanks again.  For now, it's in devel, and it might be used
in other branches if they need to be touched.
