Looking at the tests I'm wondering whether all you need is supress lints if the lint line satisfies line1 < line < line2 for some //STR_CONST?

there's also the issue of how to deal with lines like this:

x <- 'long string starting on a short
line which also has long strings in
the other parts of the body'

Before this rule, there's 3 lints, but under ignore_string_bodies=TRUE here, there are 0
