NSDocument and symlinks

[Rob Burns]

I found recently that when using Gworkspace to open a file which was 
actually a symlink to a file, the correct app would come to the 
foreground, but then display an error message stating that the "file" 
(actually the path to the symlink) couldn't be opened. These were 
NSDocument based applications. TextEdit had no problems opening 
symlinks from GWorkspace. So, I took this bit of code from TextEdit 
and put it at the beginning of  the  openDocumentWithContentsOfFile: 
display:   method of NSDocumentController.

  NSString *resolvedSymlinks = [fileName 
stringByResolvingSymlinksInPath];
  if ([resolvedSymlinks length] > 0)
    {
      NSString *standardized = [resolvedSymlinks 
stringByStandardizingPath];
      fileName = [standardized length] ? standardized : 
resolvedSymlinks;
    }

It all seemed to work ok after that. I specify opening from 
GWorkspace, because when using the Backbone projects' 'open' tool, all 
apps including NSDocument based apps worked fine (without the small 
fix). I'm not sure what the results are with the 'open' tool that 
comes with GNUstep.

Thanks
