problem with stripping NULs from input?

[Allyn Fratkin]

i submitted a patch a day or so ago to modify the lexer's use of
fgets to replace NUL characters with spaces.  the problem being solved
is that most string routines, including fgets, treat a NUL as the end
of the string.  anything past a NUL was ignored.  worse, bogofilter treated
a line that started with NUL as the end of file and stopped reading further.

i don't use -p mode so this didn't occur to me before. the lexer is now
modifying the input in such a way that it cannot be properly output
if the -p option is in use.  NULs are turned to spaces.

how serious is this in the short term?  it seems as though this
will take a bit of effort to overcome and fix.
