[GSoC][RFC/PATCH 2/2] userdiff: added shell script support, clears test

The test passes now, but imo the regex is not working, because the output of git diff with shell regex remains same as earlier it was without shell regex.

without shell regex the output was shown as: -$TEST_DIRECTORY +$TEST_DIR

with shell regex the output should be: [-$TEST_DIRECTORY-] {+$TEST_DIR+}

but even with shell regex the output is: -$TEST_DIRECTORY +$TEST_DIR

some thoughts on regex would be helpful. the shell regex is below:

+
+PATTERNS("shell",
+  /* Function Names */
+  "([A-Za-z_][A-Za-z0-9_]*)[[:space:]]*\\([[:space:]]*\\)[[:space:]]*\\{",
+  /* Words */
+  "([$#@A-Za-z_\"\'][$#@A-Za-z0-9_\"\']*)"),
+

Thanks.
