I am confused by this method name, possibly because I don't fully understand the
context of this change.

The only quotes being escaped are double quotes.  I do not understand why single
quotes are excluded.  But, since we have 2 distinct classes of quotes and only
one is being escaped, renaming this to EscapeDoubleQuotes makes more sense,
especially in the absence of comments.

I will rename this method to EscapeDoubleQuotes.

Only double quotes need to be escaped as I am quoting the strings with double
quotes.
