TortoiseGit not showing icon overlays correctly
<p>I have a fresh repo, cloned from our gerrit box.  When I check out the normal development "master" branch (named "development"), all of the icon overlays work properly.</p>

<p>The problem arises when, on that fresh clone, I check out another branch "development_test".  After checking out that branch, the icon overlay shows all files as being unversioned.  If I checkout the master branch, all is well once again.  Doesn't appear to be the underscore as other branches can be checked out without issue.  Running git status or using tortoise's "check for modifications" shows no changes.</p>

<p>Is there some setting, someplace, either on my system or on the remote, which would cause tortoise to think the tree was different enough to be considered unversioned?</p>

<p><strong>Edit</strong>: I have tried to increase the max cached icons limit to over 10k, no change.  Tried renaming the overlay key entries in the registry from "  TortoiseX---" to "  XTortoise---", also with no change.  The problem seems to be confined to this one branch.</p>

<p>Running git for windows 2.7.1.2 and TortoiseGit 1.8.16.0, both 64-bit.</p>
