The error message for implicit string concatenation read:
Error: implicit string concatenation is error-prone and disallowed in D
This was originally a deprecation message that was never updated when
it became a hard error. The self-justifying phrasing ('error-prone')
and the language name ('in D') are inconsistent with how every other
diagnostic in the compiler is worded (e.g. 'identifier expected
following module', 'declaration expected, not ...').
Simplified to:
Error: implicit string concatenation is disallowed
The supplemental hint suggesting the explicit ~ syntax is unchanged.
Updated the three affected fail_compilation tests to match.
