Unescape a path if it is quoted
Git
commands that output paths (e.g. ls-files, diff), will escape unusual characters.
@example
lib.unescape_if_quoted('"quoted_file_\\342\\230\\240"') # => 'quoted_file_☠' lib.unescape_if_quoted('unquoted_file') # => 'unquoted_file'
@param path [String] the path to unescape if quoted
@return [String] the unescaped path if quoted otherwise the original path

Private Instance Methods
Runs a git command and returns the output
@param args [Array] the git command to run and its arguments
This should exclude the 'git' command itself and global options. For example, to run `git log --pretty=oneline`, you would pass `['log', '--pretty=oneline']`
@param out [String, nil] the path to a file or an IO to write the command’s
stdout to
@param err [String, nil] the path to a file or an IO to write the command’s
stdout to
@param normalize [Boolean] true to normalize the output encoding
@param chomp [Boolean] true to remove trailing newlines from the output
@param merge [Boolean] true to merge stdout and stderr
@param chdir [String, nil] the directory to run the command in
@param timeout [Numeric, nil] the maximum seconds to wait for the command to complete
If timeout is nil, the global timeout from {Git::Config} is used. If timeout is zero, the timeout will not be enforced. If the command times out, it is killed via a `SIGKILL` signal and `Git::TimeoutError` is raised. If the command does not respond to SIGKILL, it will hang this method.
@see Git::CommandLine#run
@return [String] the command’s stdout (or merged stdout and stderr if ‘merge` is true)
@raise [Git::FailedError] if the command failed @raise [Git::SignaledError] if the command was signaled @raise [Git::TimeoutError] if the command times out @raise [Git::ProcessIOError] if an exception was raised while collecting subprocess output
The exception's `result` attribute is a {Git::CommandLineResult} which will contain the result of the command including the exit status, stdout, and stderr.
