This should have been done long long ago, but better later than never

.
I must admit that, although I tried, I failed to precisely match this convention because of "false memory" effect, and maybe also simple forgetfullness.
I propose few updates to the convention:
1. Change level of indentation to at least 4 spaces.
I don't want to start tabs vs spaces war again, but it seems that it will make somewhat easier for tab-users if the indentation was bigger. At least one person claimed that 2 spaces made it impossible for his brain to process the code (AFAIK he wanted 8-space tabs).
2. Explicitly mention if and when it is allowed (if it is) to omit curly braces, like if there's only one line after "if".
I had certain confusion regarding this rule, and kept reminding myself to check the convention, but never did. Now I see that there's no such rule at all (unless I occasionally skipped it).
3. Abbreviations in class etc naming. There are two ways to write abbreviations: always caps (GUI), CamelCase (Gui), or depending on some factor. Personally I think there's some reason I like caps more in one case and CamelCase in another, but cannot yet formulate this precisely.
I can tell I prefer to use CamelCase when the name starts with abbreviation, e.g. GuiLabel instead of GUILabel, perhaps because in the second case the abbreviation blends with the first letter of the second word.

4. Expand "Use of const" paragraph adding the use of const local variables as the way to improve readability and prevent yourself from occasional mistakes (changing precalculated variable that should not be altered later).
5. Explicitly state that it is allowed (if not preffered) to use the existing code style when making minor changes in the code which does not yet uses our convention. The idea is to keep style consistent, so, unless you are rewriting bunch of old functions, you can use the "old" AGS style.
This does not mean you can write "dirty" code ofc.
Maybe there was something else, I will post again if I remember.
UPD: Also, dumb question, but is it that literally anyone registered on forums can edit the AGS Wiki without any extra permissions and such?
