Looks excellent!

I don't know if you've been hacking on LXR yourself, but I thought I'd
let you know about some issues I've seen with parsing of Ruby files.
First: an underscore sometimes gets split apart from the word it
belongs to, and cross-referenced, as with line 139 with "def
self._load(str)" at
<http://rxr.whitequark.org/rubinius/source/kernel/common/tuple.rb>. In
that case, the text for "load" is not a link; just "_". Line 134 with
"def _dump(depth)" in the same file correctly treats "_dump" as one
word.

Another thing I notice in that file is that argument names are
sometimes cross-referenced and sometimes not; e.g. "depth" in _dump
is, but not "str" in _load. This might be related to the previous
issue.

Finally, method names like "==" and "[]" aren't cross-referenced.
