Fix ctype(3) usage on NetBSD
We need to cast value passed to isspace(3) to unsigned char to explicitly
prevent possibly undefined behavior.

CTYPE(3) Library Functions Manual CTYPE(3)
NAME
isalpha, isupper, islower, isdigit, isxdigit, isalnum, isspace, ispunct,
isprint, isgraph, iscntrl, isblank, toupper, tolower, - character
classification and mapping functions
LIBRARY
Standard C Library (libc, -lc)
CAVEATS
The first argument of these functions is of type int, but only a very
restricted subset of values are actually valid. The argument must either
be the value of the macro EOF (which has a negative value), or must be a
non-negative value within the range representable as unsigned char.
Passing invalid values leads to undefined behavior.
