Merge pull request #393 from JuliaLang/teh/error_args

Add support for multiarg InexactError, DomainError, OverflowError

README.md

@@ -159,6 +159,8 @@ Currently, the `@compat` macro supports the following syntaxes:
 * `fieldcount` is equivalent to `nfields` for Julia versions 0.6 and below and is used to
   determine the number of fields in a data type ([#22350]).
 
+* There are versions of `InexactError`, `DomainError`, and `OverflowError` that take the same arguments as introduced in Julia 0.7-DEV ([#20005], [#22751], [#22761]).
