fs: warn the user when using a remote name without a colon
A very common mistake for new users of rclone is to use a remote name
without a colon. This can be on the command line or in the config when
setting up a crypt backend.
This change checks to see if the user uses a path which matches a
remote name and gives an NOTICE like this if they do
NOTICE: "remote" refers to a local folder, use "remote:" to refer to your remote or "./remote" to hide this warning
filter: Fix incorrect filtering with UseFilter context flag and wrapping backends
In this commit
8d1fff9a8237c64f local: obey file filters in listing to fix errors on excluded files
We started using filters in the local backend so the user could short
circuit troublesome files/directories at a low level.
However this caused a number of integration tests to fail. This turned
out to be in backends wrapping the local backend. For example the
combine backend test failed because it changes the paths passed to the
local backend so they no longer match the paths in the current filter.
To fix this, a new feature flag `FilterAware` was added and the
UseFilter context flag is only passed to backends which support it. As
the wrapping backends don't support the flag, this fixes the problems
in the integration tests.
In future the wrapping backends could modify the active filters to
match the path modifications and then they could set the FilterAware
flag.
