All the qdocconf files in use for Qt 5.0 set the
codeindent variable to 1, which prefixes each line
of a snippet with one ' '. But this messes up the
cutting and pasting of snippets into editors for
actual use. qdoc now lets the codeindent variable
be initialized to 0, and then it never changes it.
This looks ok in the default formatted html output.
If the html output formatted with the template CSS
files also looks ok, then the codeindent variable
can be removed from all the qdocconf files, since
it will no longer be used by qdoc.
