Bad indentation in some cases of `try'

[jimenezrick]

The case try[...of]...catch works perfectly. But try[...of]...catch...after and try[...of]...after don't work as expected:

    try
        foo
    catch
        _ ->
            bar
    after
        fubar
end, <=== Indent wrong by -1

The next case is completely broken:

    try
        foo
after
                bar
        end,

[jimenezrick]

Very hard to fix with the current parser. When each line of code is examined to decide its indentation level, there is not easy way to differentiate between an end after a receive and another end after a try. Because the indentation level after an after in a receive is different from a try.

Fixed with the new indent code written in Erlang.
