X-Git-Tag: v2.13.2~11^2~5
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/101dd4de16eea300a59e432452fd4fc06e1ac7f2?ds=sidebyside;hp=101dd4de16eea300a59e432452fd4fc06e1ac7f2

handle_revision_arg: record modes for "a..b" endpoints

The "a..b" revision syntax was designed to handle commits,
so it doesn't bother to record any mode we find while
traversing a "tree:path" endpoint. These days "git diff" can
diff blobs using either "a:path..b:path" (with dots) or
"a:path b:path" (without), but the two behave
inconsistently, as the with-dots version fails to notice the
mode.

Let's teach the dot-dot range parser to record modes; it
doesn't cost us anything, and it makes this case work.
