[PATCH 1/2] git-gui: fix problem with "important" files not shown if, gui.maxfilesdisplayed is exceeded

[Csaba Kiraly]

gui.maxfilesdisplayed (added in dd6451f9c7c5a36d3006231b618ac6da06c7c7b4)
was applied brute force on the file list in alphabetic order. As a result,
files that had modifications might not be displayed by git-gui. Even
worse, files that are already in the index might not be displayed, which
makes git-gui unusable.

This fix changes the meaning of gui.maxfilesdisplayed, making it a soft
limit that only applies to "_O" files, i.e. files that are "Untracked,
not staged".
