[<ai...@us...>]

Revision: 11280
          http://plplot.svn.sourceforge.net/plplot/?rev=11280&view=rev

Log Message:
-----------
Implement check for parity bits in our non-binary source files.

utils/parity_bit_check.c is the C code for an app that checks for parity
bits for the stream of bytes coming from stdin.

scripts/parity_bit_check.sh is a bash script to check all our source
code files for parity bits being set except for the files listed in
scripts/parity_bit_check.exclude.  The latter list of files includes,
e.g., image files and utf8 files which go beyond the ascii subset of
utf8.
