Subject: Restored an explicit refill of the buffer in m_getfld() that I
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/e6fcf8e3c7db4549b9c2d60102fe529b6c678d25?hp=4548a3ecc4248a1d4bd4fdd45d9a2bb1e61d1e70

Restored an explicit refill of the buffer in m_getfld() that I
removed in the big stdio cleanup.  Its need is shown by reducing
the message buffer size to 2048.
