debugcommands: support wrapping long lines

If a line within a block is indented more than the line that came before,
we automatically concatenate it with the previous line. This allows us to
pretty format data. This will make tests easier to read.

At some point we may just want to evaluate entire blocks as Python
code or something, as even with this change, things aren't perfect, as we
can't e.g. have formatting like:

foo eval:[
    True
]

But this is strictly better than before, where we couldn't wrap long lines.
