At a pinch, here's how I'd do it:

| Shift+V
| 3j
| :'<,'>s/ *= */\t=\t/<Enter>
| gv
| :'<,'>retab<Enter>
| 3l
| CTRL+V
| 3l
| 3j
| d
| 3l
| CTRL+V
| 5l
| 3j
| d

* <S-V> 3j : select target lines
* :'<,'>s/ *= */\t=\t/<Enter> : spaces -> tabs around equal signน
* gv : repeat selection
* :'<,'>retab<Enter> : replace tabs by spacesน
* 3l <C-V> 3l 3j d : block-select extra spaces & delete them
* 3l <C-V> 5l 3j d : ibid.

Not as complicated as it seems: apart from <S-V> and <C-V> to select
lines or blocks, it only uses a trivial regex to substitute tabs for
spaces, and the :retab command to change them back to spaces. Most of
the keystrokes are just to move the cursor around.. something you'd have
to do anyway.

น The '<,'> range that prefixes the Ex-mode commands corresponds to the
selected lines. You don't type those 5 characters: whenever there is
an active selection, Vim conveniently does it for you..
