Implemented empty folder flag for ncdu browser interface. If there is
empty folder in the list the flag e is prepended before size. If there
is no empty folder this flag is ommited. It has the same behaviour as
original ncdu browser. (https://dev.yorhel.nl/ncdu/man)
When a directory cannot be walk-ed because of a permissions error
- or any error for that matter -, ncdu mode keeps track of the error
and highlights directories that could not be read.
Previously, the error would cause ncdu to abort.
Now, directories with unreadable sub-directories are displayed in yellow and
a message warns that the total may be underestimated.
Unreadable directories themselves are displayed in red along with the error message
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
delete files by pressing 'd' in the ncdu listing
