Function git_repository::path::absolutize

pub fn absolutize<'a>(
    path: impl Into<Cow<'a, Path>>,
    current_dir: impl AsRef<Path>
) -> Option<Cow<'a, Path>>

Resolve relative components virtually without accessing the file system, e.g. turn a/./b/c/.././.. into a, without keeping intermediate .. and /a/../b/.. becomes /.

This is particularly useful when manipulating paths that are based on user input, and not resolving intermediate symlinks keeps the path similar to what the user provided. If that’s not desirable, use [realpath()][crate::realpath() instead.

Note that we might access the current_dir if we run out of path components to pop off, which is expected to be absolute as typical return value of std::env::current_dir(). As a current_dir like /c can be exhausted by paths like ../../r, None will be returned to indicate the inability to produce a logically consistent path.
