' ' is not ASCII space; it is (the value of) the normal space character in
the execution character set.
The interesting point here is whether isprint(' ') is true in all
locales. The ISO (1990) C standard and the previous version of
the man page use exactly the same wording to explicitly say that it
is. This commit at best obfuscates this. Please back it out.
The standard is considerably less clear about whether isalpha(letter)
is true for the letters in the minimal execution character set in all
locales. This affects functions like strtol(). Is strtol("A", 0, 16)
10 in all locales? Andrey and I have been having a too-long private
discussion about this.
