Remove a spurious use of #checkName:fixErrors: that wilfully mangled filenames - it wasn't even the right thing to do since the #newFileNamed: carefully uses it within each path segment.
The writeSourceCode... method is still insane even after this. It looks like it is something left over from the partial i18n era.
See also crazy things like #multiCs.
See also the apparent complete nonsense of the supposed html flag; I can't find any places where actual html is generated and the only effect seems to be the file extension used ?
