CATCH_CONFIG_CONSOLE_WIDTH only partially effective

[arnemertz]

Description

Setting CATCH_CONFIG_CONSOLE_WIDTH to a smaller value shows that the value is honored only in some parts of the output.

Steps to reproduce

Compile this simple test case with -DCATCH_CONFIG_CONSOLE_WIDTH=20:

#define CATCH_CONFIG_MAIN
#include "catch.hpp"

TEST_CASE( "o_hello_really_long_string_over_20_chars" ) {
	REQUIRE( "Hello Catch!" == "Hello, Catch2!");
}

The output looks like this:

~~~~~~~~~~~~~~~~~~~
tests.exe is a Catch v2.2.3 host application.
Run with -? for options

-------------------
o_hello_really_lon-
g_string_over_20_c-

...................

C:\Users\marn\Documents\GitHub\hello_cmake\test\testmain.cpp(9): FAILED:
  REQUIRE( "Hello Catch!" == "Hello, Catch2!" )

===================
test cases: 1 | 1 failed
assertions: 1 | 1 failed

Except for the test case name and the separator lines, every non-empty line is longer than the configured width of 20.
