As I said below, in C++ there are more options that don't use a simple
counter, so IMHO the fully blank for you suggested would be better for
C++ rather than caring what a counter is called.

Don't know them enough.

Well I thought part of the reason for separating them into individual
languages was so each could be customised for the language, there is
no reason for them to be the same.

I should be more clear too, I mean that where there is a specific
snippet for a language lets get other opinions before changing the
behavior. For things that were default and are now language specific,
then there is no problem with customising it to suit the language.

The more I think about it the more options there are for C as well, eg
null terminated for(p=something; *p; p++), linked for(p=something; p;
p=p->next) as well as the counter so I don't know, maybe C should be
blank as well, after all the if, while and do while are blank, or
maybe for(%cursor%; %cursor%; %cursor% )?

IMHO consistency between languages is less important than being most
appropriate for the language. Files can only have one filetype so you
can't see the inconsistencies between languages without switching

Of course you shouldn't use implicit types, but there is lots of
existing code and a practice that indexes are i,j, etc

Ok, just me being confused by Gedits line wrapping (thats what patch
attachments default open in, I must change that to Geany).
