As an addendum, poking around some more I downloaded the test file, and
noticed it contains a mixture of unix and dos style line encodings:
$ file example.html
example.html: HTML document, UTF-8 Unicode text, with very long lines, with
CRLF, LF line terminators
Maybe irrelevant, but it's noteworthy that the patch immediately prior
to the one flagged above is changing behavior of handling CRLF / LF.
Essentially, patch 0016-openssl-buffering.rb-no-RS-when-output.patch is
doing:
- (...) idx = @wbuffer.rindex($/)
+ (...) idx = @wbuffer.rindex("\n")
and:
- if $/ && /\n\z/ !~ s
- s << "\n"
- end
+ s.sub!(/(?<!\n)\z/, "\n")
I don't know Ruby enough to know what's going on exactly, but the
coincidence seems odd to me, and this code feels worthy of more study.
