vim-patch:663d809: runtime(rust): Fix Rust indentation when string contains "if"

indent/rust.vim behaves incorrectly when a string literal contains the
substring "if".

For example, in this code:

    let x = "
                motif
    ";
    struct X {
                }

indent/rust.vim thinks that the closing "}" should line up with "motif".

This patch fixes the issue by checking whether the "if" is in a string
literal or comment before considering it to be a match for a subsequent
brace (and also by requiring it to start on a word boundary).

Add an indent test to ensure this does not regress.

closes: vim/vim#19265
