commit 86c63a8251496f1272902185f4b9a0ddcc023815
Author: Mark H Weaver <address@hidden>

    Remove null string optimization from scm_from_stringn
    
    * libguile/strings.c (scm_from_stringn): Always return a freshly
      allocated string from scm_from_stringn, even when asked to construct
      the null string, in accordance with the R5RS.  Previously, we
      optimized the null string case by returning a reference to a global
      null string object (scm_nullstr).
