|
* 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!
