Peter Eisentraut 8b3e2c622a Fix pg_isblank() ... There was a pg_isblank() function that claimed to be a replacement for the standard isblank() function, which was thought to be "not very portable yet". We can now assume that it's portable (it's in C99). But pg_isblank() actually diverged from the standard isblank() by also accepting '\r', while the standard one only accepts space and tab. This was added to support parsing pg_hba.conf under Windows. But the hba parsing code now works completely differently and already handles line endings before we get to pg_isblank(). The other user of pg_isblank() is for ident protocol message parsing, which also handles '\r' separately. So this behavior is now obsolete and confusing. To improve clarity, I separated those concerns. The ident parsing now gets its own function that hardcodes the whitespace characters mentioned by the relevant RFC. pg_isblank() is now static in hba.c and is a wrapper around the standard isblank(), with some extra logic to ensure robust treatment of non-ASCII characters.
