indent butchered Objective-C formatting. This patch was created by: 1) Reverting the indent changes in hw/xquartz 2) Editing X11Application.m and chaning some #ifdef logic to work with uncrustify 3) Hand edited some (c) notifications 4) Opened all XQuartz sources in XCode and re-indented (^I) 5) Ran uncrustify with this configuration (as close to the indent rules as I could get): tok_split_gte=false utf8_byte=true utf8_force=true
