* guile-snarf-docs.in, guile-snarf-docs-texi.in: rewrite &
simplify.
* eval.c: all hash signs are in column 0.
* Makefile.am (guile_filter_doc_snarfage): build using
c-tokenize.c, not filter-doc-snarfage.c.
rearrange snarfing dependencies a bit.
* c-tokenize.lex: new file.
filter-doc-snarfage.c: new files.
* Makefile.am: add stuff to [build,] use and distribute
guile-snarf-docs, guile-snarf-docs-texi, guile_filter_doc_snarfage.
* guile-snarf.in: grok the new snarf output.
* snarf.h: make the output both texttools- and `read'-friendly.
* guile-doc-snarf.in (bindir): reimplement in terms of guile-snarf
and guile-snarf-docs. (should also deprecate, I guess. maybe
not).
