BUG: shell-safe-rm can't deal with symbolic links on Linux

[bunop]

shell-safe-rm can't deal with symbolic links pointing to directories, for example:

$ export SAFE_RM_DEBUG=1
$ cd /tmp/
$ mkdir test
$ ln -s test test_link
$ rm test_link
[D] file test_link
[D] 1 files or directory to process: test_link
[D] ls_result: test_link
[D] 216: test_link: is a directory
safe-rm: test_link: is a directory
[D] remove returned status: 1
[D] EXIT_CODE 1

The only way to delete a link to a directory is to pass -r parameter, unlike the standard rm will do:

$ rm -r test_link
[D] short option -r
[D] file test_link
[D] recursive    : -r
[D] 1 files or directory to process: test_link
[D] ls_result: test_link
[D] trash test_link
[D] mv test_link to /home/developer/.local/share/Trash/files/test_link-2017-03-31_12:25:11-0
[D] 254: trash returned status 0
[D] remove returned status: 0
[D] EXIT_CODE 0

I think I've resolved this issue, I will submit a PR
