Extra indent in Vi/Vim Tcl code block indentation

Question

I am using the gg=G, =ap etc. paradigms to reformat some code. This code is in tcl:

proc something { foo bar } {
set foo [yadda yadda]
set foo [yadda yadda]
set foo [yadda yadda]
}

When I try adjust indents, the formatting changes to:

proc something { foo bar } {
    set foo [yadda yadda]
        set foo [yadda yadda]
        set foo [yadda yadda]
}

I would expect all the set statements at the same indent level. Is there a way to do that?

This is the "VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Apr 4 2017 18:14:54)" what comes with MacS Sierra, invoked as "vi".

Thanks

Is the &filetype properly detected? Vim 7.4 runtime should already include the correct indent file.

Execute :scriptnames to list all sourced files and look for /usr/share/vim/vim74/indent/tcl.vim.

If it's missing, make sure you have this line in your vimrc file:

filetype plugin indent on
