C# 7.x §B.3 does not mention implementation-defined limit of §6.5.8 #line directive

[KalleOlaviNiemitalo]

Describe the bug

In the C# 7.x draft, §B.3 (Implementation-defined behavior) does not list this one from §6.5.8 (Line directives):

The maximum value allowed for Decimal_Digit+ is implementation-defined.

Example

None.

Expected behavior

List that one, too.

Additional context

It was added to standard/portability-issues.md in #759 but removed again in 3a94e2b, which was then merged via #238 and #795.

All other post-6.0 implementation-defined behaviors seem to be listed. I did not search for post-6.0 undefined or unspecified behaviors.

Fixed in #863
