Enables the automatic adornment of code blocks by the \smaller command/environment provided by the LaTeX relsize package (cf. <http://www.ctan.org/tex-archive/macros/latex/contrib/relsize>).

Only the `CODE` and `VERBATIM*` cases in `latex.c` have been altered. The respective output is now preceded by `\\ifx\\smaller\\undefined \\relax \\else <applied relsize macro> \\fi`. By embedding the `relsize` commands in a conditional TeX block, the availability of the `relsize` commands is reassured.
