[PATCH 0/1] add 'mv' errmsg filter and apply in generic/682

[PATCH 0/1] add 'mv' errmsg filter and apply in generic/682

[Ferry Meng]

Hi, all:

I have noticed that after coreutils 9.4+, generic/682 will meet the same mismatch output
just like generic/245 (commit d9323ad :'generic/245: Filter mv error message').
To fix this, we can seperate the filter ,move it into common 
directory as '_filter_mv_err_msg' and apply it to similar cases.

Attention: in generic/419 and generic/369, there also exists "cannot move ... to ..." 
output. After testing, generic/419 don't need to apply filter. But I don't know how to 
enable 'richacl' on my filesystem, so I can't verify if generic/369 needs to be fixed.

  generic/682: apply 'mv' error message fitler.

[PATCH 1/1] generic/682: apply 'mv' error message fitler.

[Ferry Meng]

As coreutils update to 9.4+, the 'mv' command change also results in
the mismatch output of generic/682.

This case is similar to generic/245, you can refer to 'generic/245:
Filter mv error message'(commit d9323ad7a0). Now seperate this filter
as '_filter_mv_err_msg', move it into common/filter, and apply in
generic/682.
