&syntax is completely irrelevant, it is only used for highlighting.
What you need is normally managed by indentation scripts placed in
`{runtimepath}/indent/{filetype}.vim` (uses &filetype). But in
addition to indentation scripts there are default values, specifically
all options containing indent are relevant: `:helpgrep
\*'\w*indent\w*'\*` (or use the same search in `:h options.txt`). Also
there may be option values leaked from previously open filetypes or
global settings set in vimrc/etc.

The easiest solution should be `:setlocal indentkeys-=:`, but this
will only disable reindenting on colon. Vim will *still* think that
line needs to be shifted to the start, yet it will not autoindent when
you type colon.
