OK so you mean the window staying open when switching to idle mode.

This is due to a difference in default option values: git has -fixed-vo
enabled by default, meaning that the same window is kept open and reused
when switching to a different video of reconfiguring during one video.
svn has -nofixed-vo by default. The idle mode behavior is a side effect
of this (with -nofixed-vo the window is completely destroyed when a
video is closed, with -fixed-vo it stays around for reuse).

You can get the same behavior as in svn by using the -nofixed-vo option.
However that has some negative effects; the non-fixed-vo behavior is
especially annoying when playing Matroska files with ordered chapters,
which results in some window reconfiguration events (this doesn't matter
in svn since svn completely lacks support for playing ordered chapters
at all). It should be no worse than svn though.
