[mario-campos]

This patch fixes bug #1081 by adding an underscore _ before the number ('0'..'9') in the C source.

Since this affect code generation on a very large scale, I'm hesitant to pull this. I'll wait for approval from @Araq

I think @Araq already said that he dislikes this PR.

Relevant IRC discussion:

(08:30:40 PM) Araq: xenagi: not really
(08:31:04 PM) xenagi: why not?
(08:32:24 PM) Araq: I think it's more complex than necessary
(08:34:59 PM) xenagi: hmm, i suppose some of those cases could be cascaded
(08:35:22 PM) flaviu: Couldn't it be done by just adding the underscore in all cases?
(08:35:46 PM) xenagi: yes
(08:35:51 PM) xenagi: should it?
(08:36:16 PM) Demos: ermmmm reserved names ahoy
(08:38:33 PM) flaviu: Araq: What do you think about appending _ to every name?
(08:38:50 PM) Araq: it's crap.
(08:38:57 PM) dom96: Why _?
(08:39:10 PM) dom96: Append 'ID' if the identifier begins with a number.
(08:39:22 PM) xenagi: _ would not hinder readability of the variable name
(08:39:35 PM) ***Araq hates C's __ASCII_ART__

@iamrekcah in such a case, commit the whitespace changes into one commit and the relevant code changes into another commit.

Closed, as another PR solved this issue a bit more gracefully (according to Araq)
