The latter.  It was renamed much later, in revision 100942.  26091 was
one of the revisions that changed the file under its old name.

Will do.

I assumed "bzr log" should work because "bzr diff" has no problems
with the new name.  E.g., "bzr diff -c26091 src/s/usg5-4-common.h"
shows the diffs for src/s/usg5-4.h, as I'd expect.
