Well, I think all coders probably think that way in general... though one
thing I have been told is that I am good at adapting my coding style to that
of the project I am working on. Unless, of course, I start the project, then
in that case my coding style is The Best(tm) as well! :)

I never cut-and-paste code, that is just asking for trouble, and you also
don't really learn much either. Generally, if I use third-party code I
manually insert it into the code. Or, if the patch is considerable I will
patch the code in and then manually use a visual diff program to look over
the changes and make any necessary changes to adapt the code to the style of
the codebase. Blind copying and pasting is just a recipe for disaster, I
always try to understand the code I am adding to any project so there are no

That just makes the code easier to read and maintain, so makes sense!

Yes, indeed I do. Though in the case of Lua it would be less "just copy this
patch into the codebase" and more "adapt the ideas presented into the
codebase". I get the feeling the latter has happened, and upon reflection I
do understand why the former would not be done.
So far, with my custom Lua variant, I think I have done a good job of
adhering to the style that Lua uses. Though, honestly, I think Lua could use
a good code tidying pass as it is really obvious where different authors
have created code... why single character indenting in luac.c lhf, why? ;)
Actually, speaking of that... I remember a utility from years ago that would
reformat the source code for C, it had a *ton* of options to control every
possible code formatting scenario (placement of braces, etc). I can't for
the life of me remember what the program was called... anyone know?
Eventually I would like to do a from-scratch build of my Lua variant in my
own style, but for now I am just building on the vanilla version. At this
point I think I grok a significant portion of Lua, I am aiming for 100%!
