Log Message:
Ignore non-numeric values for HISTSIZE
This is a temporary change (which can be pulled up to -9 and -10)
to avoid having
HISTSIZE=foo /bin/sh
cause sh to fail to start.
A better change, but one requiring far more code changes, so that
bad HISTSIZE is ignored, only when read from the environment, but
will be an error otherwise, will come later.
XXX pullup -9, -10
