The Hydra buildfarm provides code coverage analysis. For some reason,
in some test cases, code coverage data seem to be incompatible, and
generate error messages at parser run-time. Ignore these messages so
that (i) these tests do pass, (ii) coverage results be provided by
Hydra.
* tests/local.at (AT_PARSER_CHECK): Ignore messages for failed merges
of code coverage/profiling results.
* gnulib: Fix install-pdf in po/ and runtime-po/.

than the defined entity as main entity, as it results in
an incorrect index. For instance, don't document
{return YYERROR;}, which results in a single index entry
"return YYERROR;", but rather as typed function whose
return type is "type", and whose argument list is ";".
For some reason it seems that texi2dvi -o no longer forces --clean

since TeX is run from there.
