Code Issues Releases Wiki Activity

Another round of tweaks

Browse source 
Notable changes:
- Change a bunch of uses of memcmp(3) to compare strings (which can
  cause buffer read overflows) to strncmp(3).
- src/cmd/ksh93/include/name.h: Eliminate redundant Nambfp_f type.
  Replace with Shbltin_f type from libast's shcmd.h. Since that is
  not guaranteed to be included here, repeat the type definition
  here without fully defining the struct (which is valid in C).
