The comment moved is referring to the --output-asm-syntax flag rather
than the --print-imm-hex flag, but seems to have mistakenly been put
under the definition of that flag due to some misplaced line numbers on
phabricator.
Currently the filetype flag is not documented, and knowing the behavior
of this flag is fairly important for doing anything other than
disassembling to text assembly.
