Is "diff -B -c" the correct way of submitting patches against ".lyx" documentation?

[John C. McCabe-Dansted]

I have made a patch against References.lyx. (posted to -doc) 

This patch includes a suggestion to use "diff -B -c" to create patches against 
lyx files. These are the only set of options to diff I found that did not 
corrupt the whitespace in References.lyx or create hundreds of irrelevant 
changes due to automatic reformatting of the entire References.lyx file.

However, I would like to check: are these the correct flags we should use for 
diff-ing .lyx files?
