This is not a locale problem, because I see it in C locale too.
[digs] Apparently this is an oversight in the new regex code we
lifted from Tcl 8.4.1:

switch ((enum classes) index)
{
case CC_PRINT:
case CC_ALNUM:
cv = getcvec(v, UCHAR_MAX, 1, 0);
if (cv)
{
for (i = 0; i <= UCHAR_MAX; i++)
{
if (pg_isalpha((chr) i))
addchr(cv, (chr) i);
}
addrange(cv, (chr) '0', (chr) '9');
}
break;

in other words, :print: is the same as :alnum:. This is obviously
a bug, will fix ... wonder if Henry Spencer knows about it?
