autom4te: don't filter out portions of location traces
* bin/autom4te.in (_m4_warn): Pass warnings through the channels
machinery as a single chunk, to avoid partial filtering.
* lib/m4sugar/m4sugar.m4 (_m4_warn): Document the conventions.
* tests/m4sugar.at (m4@&t@_warn): Enhance test to catch this.
