merge_submodule() stores errors using path_msg(), whereas other call sites make use of the error() function. This is inconsistent, and moving towards path_msg() seems more friendly for libification efforts since it will allow the caller to determine whether the error messages need to be printed. Note that this deferred handling of error messages changes the error message in a recursive merge from error: failed to execute internal merge to From inner merge: error: failed to execute internal merge which provides a little more information about the error which may be useful. Since the recursive merge strategy still only shows the older error, we had to adjust the new testcase introduced a few commits ago to just search for the older message somewhere in the output.
