Is this plugin specific to python source code? Or can it auto-align (for 
example) C code as well?

Setting replacing the entire text has a serious drawback. The undo 
action that is recorded by scintilla will be large in memory, basically 
the size of the document. It seems auto-aligning is a frequent thing so 
this sounds troublesome.
