Fix printing of strings inside functions

[ChrisJefferson]

Previously we normalised all whitespace in printed out functions, which would affect whitespace inside strings.

Previously we would print out functions, then to get rid of all whitespace using NormalizeWhitespace. However, this would also normalise whitespace inside strings.

Why do we modify the whitespace at all?

[ChrisJefferson]

Guessing, I assume it is because we want the String to be a single line, and concatenating the lines together would create huge spaces from indendantion.

Seems to do the job nicely, thanks, but I have a question and a suggestion.

[ChrisJefferson]

There were several issues with this PR, but most of the code disappeared while fixing @fingolfin's comment (as removing formatting removed the indentation I needed to get rid of)

Thanks
