* movemail.c: Remove unused vars

lib-src/ChangeLog

 2011-02-21  Paul Eggert  <eggert@cs.ucla.edu>
 
 	* movemail.c (main, pop_retr): Rename locals to avoid shadowing.
+	(progname, sfi, sfo, ibuffer, obuffer): Remove unused vars.
 
 	Declare file-scope functions and variables static if not exported.
 	This is more consistent, and is nicer with gcc -Wstrict-prototypes.
