style fix: add space after 'for' operator

[wilzbach]

It turns out that I forgot to sed for for and there was an double occurrence of foreach in std/encoding.d.
I am terribly sorry for the spam.

It adds spaces after "for" key, but what about:

for ( int i = 0; i < indent; i++ )

vs

for (int i = 0; i < indent; i++)

?

Never seen the first style in Phobos, so the latter is prefered I guess.

I see it. For example on changed files for this pull request:

std/concurrency.d 1989, 2133, ...

I think it can fix this too.

I think it can fix this too.

@trikko do you mean "I"?
Don't forget to add a regex to check for this in the future to the .travis.yml then ;-)

Yes, I wrote "I think" 👍 eheh.
