Bug 1074911 - Replace JS_ASSERT by MOZ_ASSERT. r=jorendorff Apply the following script sed -i ' /JS_ASSERT(/ { s/JS_ASSERT(/MOZ_ASSERT(/; :b; s/ \\$/\\/; /;/ { p; d; }; n; s/^/ /; b b; }; s/JS_ASSERT (/MOZ_ASSERT(/; ' Except where the JS_ASSERT macro does not end with a semi-colon, where empty lines are in the middle of the macro, and where the backslahes are always the same-length after the expression.
