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. Signed-off-by: Michael Montalbo <mmontalbo@gmail.com>
`git log -L` has bypassed log_tree_diff() and log_tree_diff_flush() since the feature was introduced, short-circuiting from log_tree_commit() directly into line_log_print(). This skips the no_free save/restore (noted in a NEEDSWORK comment added by f8781bf), the always_show_header fallback, show_diff_of_diff(), and diff_free() cleanup. Restructure so that -L flows through log_tree_diff() -> log_tree_diff_flush(), the same path used by the normal single-parent and merge diff codepaths: - Rename line_log_print() to line_log_queue_pairs() and strip it down to just queuing pre-computed filepairs. The show_log(), separator, diffcore_std(), and diff_flush() calls are removed since log_tree_diff_flush() handles all of those. - In log_tree_diff(), call line_log_queue_pairs() then log_tree_diff_flush(), mirroring the diff_tree_oid() + flush pattern used by the single-parent and merge codepaths. - Remove the early return in log_tree_commit() that bypassed no_free save/restore, always_show_header, and diff_free(). Because show_log() is now deferred until after diffcore_std() inside log_tree_diff_flush(), pickaxe (-S, -G, --find-object) and --diff-filter now properly suppress commits when all pairs are filtered out. The blank-line separator between commit header and diff changes slightly: the old code printed one unconditionally, while log_tree_diff_flush() only emits one for verbose headers. This matches the rest of log output. Also reject --full-diff, which is meaningless with -L: the filepairs are pre-computed during the history walk and scoped to tracked paths, so there is no tree diff to widen. Update tests accordingly.

Now that -L flows through log_tree_diff_flush() and diff_flush(), metadata-only diff formats work because they only read filepair fields (status, mode, path, oid) already set on the pre-computed pairs. Expand the allowlist in setup_revisions() to also accept --raw, --name-only, --name-status, and --summary. Diff stat formats (--stat, --numstat, --shortstat, --dirstat) remain blocked because they call compute_diffstat() on full blob content and would show whole-file statistics rather than range-scoped ones.

Since its introduction, git log -L has short-circuited from
log_tree_commit() into its own output function, bypassing
log_tree_diff() and log_tree_diff_flush(). This skips no_free
save/restore, always_show_header, diff_free() cleanup, and
means that pickaxe (-S, -G, --find-object) and --diff-filter
cannot suppress commits whose pairs are all filtered out, because
show_log() runs before diffcore_std().
This series restructures the flow so that -L goes through the
same log_tree_diff() -> log_tree_diff_flush() path as normal
single-parent and merge diffs, then uses that to enable several
non-patch diff formats.
Patch 1: revision: move -L setup before output_format-to-diff derivation
Preparatory reorder in setup_revisions(). The -L block sets a
default DIFF_FORMAT_PATCH when no format is requested; move it
before the derivation of revs->diff from output_format so the
default is visible to that check. No behavior change on its own.
Patch 2: line-log: integrate -L output with the standard log-tree pipeline
Rename line_log_print() to line_log_queue_pairs(), stripping it
down to only queue pre-computed filepairs. log_tree_diff_flush()
handles show_log(), diffcore_std(), and diff_flush(). This
fixes pickaxe and --diff-filter suppression, and aligns the
commit/diff separator with the rest of log output. Also rejects
--full-diff, which is meaningless when filepairs are pre-computed.
Patch 3: line-log: allow non-patch diff formats with -L
Expand the allowlist to accept --raw, --name-only,
--name-status, and --summary. These only read filepair metadata
already set by the line-log machinery. Diff stat formats (--stat,
--numstat, --shortstat, --dirstat) remain blocked because they
call compute_diffstat() on full blob content and would show
whole-file statistics rather than range-scoped ones.
