Error in Window log when editor tab is open with file using Windows Long Path API.

[msftrncs]

Referencing microsoft/vscode#284345, I get an error message in the Window log each time a VS Code editor tab is activated or actively editing a file where the path is longer than 260 characters causing Windows to switch to Windows Long Path API.

The path to this file is \\?\UNC\USNEFS100.rosenbauer.local\Engineering\Programming\Aerials\LCS Y2020\y2020_controller\local_builds\2512\251216\RNE_Aerial_Dev\162221_5cf5637b6_cmorris\23461B-001_ID025_Aux_Control_Platform_Leveling_Y2020_TTC2310\23461B-001_ID025_Aux_Control_Platform_Leveling_Y2020_TTC2310_controller.log or 290 characters before the Windows Long Path API mechanism added 6 more characters.

@msftrncs,

Thank you. I'll take a look as soon as I get access to a Windows machine.
