I've inherited a legacy Rails app that runs on Ruby 1.8.6. I want to upgrade to 1.8.7, but I get weird bugs. One of them was a weird CSS glitch. Here's what happens:

Note how input.html.erb renders <div id="ribbon"> and then a partial. If you look at the output, the partial gets rendered in both versions of Ruby, but the <div id="#ribbon"> gets rendered only in 1.8.6. It appears that the culprit is the small fragment containing a ruby comment <% #end top div %>. If I remove it, both work the same.

Is this an ERB issue and why does switching Ruby versions trigger it?

# An improved (although heavily obfuscated) version of @garybernhardt's
# git pretty log, show in Destroy All Software №63. Said improvements are:
#
# * Minimize the whitespace between the columns - use a single space instead
#   of whatever the color codes require
# * Colorize the graph, as with git log --graph
# * Slightly simplify the sed regular expression
#
