diagnostics: fix invalid error message indentation

Browse Source 
https://lists.gnu.org/archive/html/bison-patches/2019-08/msg00007.html

When Bison is started with a flag that suppresses warning messages, the
error_message() function can produce a few gigabytes of indentation
because of a dangling pointer.

* src/complain.c (error_message): Don't reset indent_ptr here, but...
(complain_indent): here.
* tests/diagnostics.at (Indentation with message suppression): Check
this case.
