Description: Fixes for #235965
When I run cstocs without arguments, following warning is printed:
  
  Use of uninitialized value in pattern match (m//) at /usr/bin/cstocs line 135.

Attached cstocs.patch solves the issue by checking whether ARGV[0] is
defined before using it.

I also attach another patch which fixes minor typo in dbfcstocs
documentation.  See dbfcstocs.patch.
