From: Michael Montalbo <redacted> The line_level_traverse block sets a default DIFF_FORMAT_PATCH when no output format has been explicitly requested. This default must be visible to the "Did the user ask for any diff output?" check that derives revs->diff from revs->diffopt.output_format. Currently the -L block runs after that derivation, so revs->diff stays 0 when no explicit format is given. This does not matter yet because log_tree_commit() short-circuits into line_log_print() before consulting revs->diff, but the next commit will route -L through the normal log_tree_diff() path, which checks revs->diff. Move the block above the derivation so the default DIFF_FORMAT_PATCH is in place when revs->diff is computed. No behavior change on its own.
