I tried that, but most of the results (and there are a ton to wade through)
are function parameters that wrapped and align with the opening paren on
the next line.

Earlier in the thread (i think it was this thread anyway) i posted a bash
incantation that will grep the source tree and return all lines with >= N
leading spaces sorted descending by number of leading spaces. The highest
was about 160 :)

If you search lldb-dev for awk or sed you'll probably find it
