Return path to the Git sub-command executables (the same as
C<git --exec-path>). Useful mostly only internally.

=item hash_object ( TYPE, FILENAME )
-=item hash_object ( TYPE, FILEHANDLE )
-
Compute the SHA1 object id of the given C<FILENAME> (or data waiting in
C<FILEHANDLE>) considering it is of the C<TYPE> object type (C<blob>,
C<commit>, C<tree>).
-In case of C<FILEHANDLE> passed instead of file name, all the data
-available are read and hashed, and the filehandle is automatically
-closed. The file handle should be freshly opened - if you have already
-read anything from the file handle, the results are undefined (since
-this function works directly with the file descriptor and internal
-PerlIO buffering might have messed things up).
-
The method can be called without any instance or on a specified Git repository,
it makes zero difference.
The function returns the SHA1 hash.
