print an error message for invalid path

dmpot · spearce · commit 7e7abea96b81 · 2008-10-12T12:36:19.000-07:00
If verification of path failed, it is always better to print an
error message saying this than relying on the caller function to
print a meaningful error message (especially when the callee already
prints error message for another situation).

Because the callers of add_index_entry_with_check() did not print
any error message, it resulted that the user would not notice the
problem when checkout of an invalid path failed.
