/*
 * VFS for Git is incompatible with FSMonitor.
 *
 * Granted, core Git does not know anything about VFS for Git and we
 * shouldn't make assumptions about a downstream feature, but users
 * can install both versions.  And this can lead to incorrect results
 * from core Git commands.  So, without bringing in any of the VFS for
 * Git code, do a simple config test for a published config setting.
 * (We do not look at the various *_TEST_* environment variables.)
