test-lfs: add coverage for the binary() fileset This ensures that the blobs don't need to be present to be filtered properly.

fileset: use filectx.isbinary() to filter out binaries in eol() Since LFS stores the binary attribute in the pointer file, this means that the file doesn't need to be downloaded in order to be skipped. This function also catches an IOError if the data can't be loaded in the non-LFS case. I wonder if it's worth storing the unix/dos attributes in the pointer file as well, though I'd expect LFS files to be binary most of the time.

crecord: re-center display in interactive curses commit on pageup/down A long-standing issue in the crecord (interactive curses commit interface) is that using PageUp/Down to move along longer-than current screen size chunks would "lose" the cursor and not properly re-center. There has been self.recenterdisplayedarea() to do that, but it has not been in use for some reason. Add calls to the appropriate uparrowshiftevent() and downarrowshiftevent() methods to fix this.
