From 355687b644f274cf73b658e075bdd9947583559c Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Sat, 5 Mar 2011 15:38:55 +0100 Subject: Ensure key descriptions in status bar are always null-terminated. Key descriptions are just strncpy()'ed to key[], with KEYS_KEYLEN as maximum character count. This leads to a non-null-terminated string if the source pointer actually points to a string with a length of KEYS_KEYLEN bytes. Always appending a null character fixes this.
