merge request diff highlighting confused by removed line of dashes

[Samuel Bronson]

https://code.launchpad.net/~naesten/quadra/vc2005express-build/+merge/27439 is where I spotted this: I was puzzling over the black line of dashes in the midst of a removed region, until I realized that it was a removal too, but had somehow escaped highlighting.

The line in question is line 81 in the following snippet:

80 -How to build ZLIB on Windows
81 -----------------------------
82 -I am using zlib-1.2.3 and like libpng, newer version should work too. Open
83 -up zlib-1.2.3\projects\visualc6\zlib.sln (or zlib.dsw if the solution does
84 -not exist, and Visual Studio will ask to create a solution). Select the
85 -configuration as 'LIB Release', Edit the project setting. In
86 -'Configuration Properties' / 'C/C++' / 'Code Generation', make sure that
87 -'Runtime Library' is set to 'Multi-Thread (/MT)'. Build.
