printer: bug: fallback syms printed without prefix.
This is a basic read/print consistency problem. When a symbol is printed that is anywhere in the fallback list of the current package, we are dumping it unqualified, even if it is hidden by a same-named symbol in the current package itself or such a symbol occurring earlier in the fallback list. * lib.c (symbol_needs_prefix): When the to-be-printed symbol is found in the fallback list, re-scan the current package for a symbol having the same name, as well as the preceding nodes in the fallback list. If such a symbol is found, then the to-be printed symbol must be package-qualified. * tests/012/syms.expected: New file. * tests/012/syms.tl: Likewise. * tests/012/compile.tl: Pull syms into compile job. * txr.1: Clarify text about this. The existing text's only reasonable interpretation supports the behavior which this patch ensures (which is needed on grounds of read/print consistency) but the text lacks precision.
