Cloning a repo on Windows breaks symlinks #4107
Description
I can't clone faithfully repos with symlinks on Windows. I have been able to do this using Git for Windows (info) when in Administrator mode and setting core.symlinks=true.
Reproduction steps
I am using libgit2 through R with the git2r package.
Start R in administrator mode
> git2r::config()
programdata:
color.branch=auto
color.diff=auto
color.interactive=true
color.status=auto
core.autocrlf=true
core.fscache=true
core.symlinks=true
diff.astextplain.textconv=astextplain
help.format=html
http.sslcainfo=C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt
rebase.autosquash=true
global:
core.symlinks=true
filter.lfs.clean=git-lfs clean -- %f
filter.lfs.process=git-lfs filter-process
filter.lfs.required=true
filter.lfs.smudge=git-lfs smudge -- %f
> git2r::clone("git://github.com/imbs-hl/ranger.git", "C:/Users/USER/Documents/GitHub/ranger2", progress = FALSE)
Local: master C:/Users/USER/Documents/GitHub/ranger2/
Remote: master @ origin (git://github.com/imbs-hl/ranger.git)

Expected behavior
Expect many symlink files in ranger-r-package/ranger/src folder.
Actual behavior
Many text files in ranger-r-package/ranger/src folder where file contents are the original symlink target paths.
