virtualfilesystem: fix bug with symlinks being ignored

benpeart · dscho · commit c3e50d87c177 · 2018-12-15T19:36:43.000+01:00
The virtual file system code incorrectly treated symlinks as directories instead of regular files. This meant symlinks were not included even if they are listed in the list of files returned by the core.virtualFilesystem hook proc. Fixes #25 Signed-off-by: Ben Peart <Ben.Peart@microsoft.com>
