#1337 candle.exe -p includes extra line number info

[Scott Kurtzeborn]

When using the WiX preprocessor to preprocess XML files the output includes line number information. For normal usage scenarios, this is problematic because what is usually desired is the pure output without inserting any additional information used internally by WiX tools.

Proposal: To avoid breaking anyone who might actually be using this line number information in the preprocessed output we should add a new preprocess command line argument to clean the output produced.

This doesn't look like it's coming in. It could be added as feature request later if desired.
