Trivial DMD fixes: GitHub pull requests vs. Bugzilla issues

[David Nadlinger]

For almost a month now, I have a trivial pull request open for DMD: 
https://github.com/D-Programming-Language/dmd/pull/10. It's only about 
adding the word »length« in two places to clarify the tuple 
out-of-bounds error message, so I didn't bother to open a ticket for it 
because I figured that it would only create unneeded administrative 
overhead for such a small change.

However, given that the commit has not been merged yet: Walter, do you 
still prefer Bugzilla issues for this kind of patches?
