/*
* FILECOMP.C - handles filename completion.
*
*
* Comments:
*
* 30-Jul-1998 (John P Price <linux-guru@gcfl.net>)
* moved from command.c file
* made second TAB display list of filename matches
* made filename be lower case if last character typed is lower case
*
* 25-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Cleanup. Unicode safe!
