Unable to anchor a file pattern in filter.List().

[middelink]

I have a daily "-x / /boot" backup from my rp3, it contains (among other files) /bin/uncompress and /bin/gunzip which are hardlinked to eachother. To test if this works I wanted to restore them, so I ran:
$ mkdir z
$ restic -r ... restore --include bin/uncompress --include bin/gunzip -t z
And to my surprise I ended up with
z/bin/gunzip
z/bin/uncompress
z/usr/lib/klibc/bin/gunzip

Prefixing the include with a / wont work as the repo does not seem to contain the root prefix when calling the selectFilter(), so it won't match anything. filter.List also does not seem to have any anchoring characters. Seeing it defines ** to match multiple directories, I would guess the intent was to have Match anchor the pattern at the beginning of the string. E.g. it showing behavior of me having typed --include **/bin/gunzip

Output of restic version

restic 0.4.0 (v0.4.0-76-g4f5e9e9-dirty)
compiled with go1.8 on linux/amd64

Expected behavior

Two files:
z/bin/gunzip
z/bin/uncompress

Actual behavior

Three files appear:
z/bin/gunzip
z/bin/uncompress
z/usr/lib/klibc/bin/gunzip

Steps to reproduce the behavior

have a repository, backed up from / with both say
/bin/fileA
/usr/bin/fileA
$ restic -r ... restore --include bin/fileA -t z
you end up with both files under z/

Interesting, thanks for opening this issue. It may indeed be a bug.

Ha, this is actually an old bug that I haven't gotten around to fixing (#374), thanks for reminding me!
