releases, a nonzero 'c' argument meant that the input string could be
terminated by either that character or \0.  Recent refactoring broke
that, causing the thing to scan for 'c' only.  This went undetected
because no part of the main code actually passes nonzero 'c'.  However
it broke tsearch2 and possibly other user-written code that assumed
the old definition.  Per report from Tom Hebbron.

conn->ssl isn't set yet and we aren't expecting more than one byte.
The advantage is that we will correctly detect loss-of-connection
instead of going into an infinite loop.  Per report from Hannu Krosing.

user documentation.

consistent.  On Unix we now always consult getpwuid(); $HOME isn't used
at all.  On Windows the code currently consults $USERPROFILE, or $HOME
if that's not defined, but I expect this will change as soon as the win32
hackers come to a consensus.  Nothing done yet about changing the file
names used underneath $USERPROFILE.
