[bug-gnulib] null vs. `NUL byte'

[Jim Meyering]

I've always written `NUL' to indicate the zero byte, '\0', not `null',
because the latter is easy to confuse with the NULL pointer, which is
usually at least 4 bytes.  Paul, any objection?

2005-03-26  Jim Meyering  <address@hidden>

        * intprops.h: Say `terminating NUL byte' rather than `terminating null'.
        * quotearg.c: Likewise.
        * filemode.c: Likewise.
