Subject: bug#21744: 24.5; diff-mode highlight only suitable part
Date: Fri, 23 Oct 2015 17:55:47 +0300	[thread overview]
Message-ID: <20151023145547.GA4307@whiterain> (raw)

For example let's I have such content of *vc-diff*

diff --git a/cmake/FindLibClang.cmake b/cmake/FindLibClang.cmake
index 8aa7689..62b5b08 100644
--- a/cmake/FindLibClang.cmake
+++ b/cmake/FindLibClang.cmake
@@ -72,7 +72,7 @@ if (NOT LIBCLANG_CXXFLAGS)
     endif ()
     set(LIBCLANG_CXXFLAGS "-I${LIBCLANG_CXXFLAGS}")
   endif ()
-  string(REGEX REPLACE "-([Og][0-9]*|std=c\\+\\+..|(W|f)[a-zA-Z-]*|DNDEBUG) ?" "" LIBCLANG_CXXFLAGS "${LIBCLANG_CXXFLAGS}")
+  string(REGEX REPLACE "-([Og][0-9]*|std=c\\+\\+..|(W|f)[=a-zA-Z-]*|DNDEBUG) ?" "" LIBCLANG_CXXFLAGS "${LIBCLANG_CXXFLAGS}")
   set(LIBCLANG_CXXFLAGS ${LIBCLANG_CXXFLAGS} CACHE STRING "The LLVM C++ compiler flags needed to compile LLVM based applications.")
   unset(LIBCLANG_CXXFLAGS_HACK_CMAKECACHE_DOT_TEXT_BULLSHIT CACHE)
 endif ()

the diff-mode highlight string with starting "-" with red, and starting "+" with green,
it would be great if it  highlight also difference between strings.
There is only "=" symbol difference between two lines above, so it would be great
if emacs highlight also "=" in the second string.

You can see how github doing this:
