Minix editline v0.2.1

Browse Source 
=====================

Fix Debian batch mode reader, read_redirected(), which is activated
when input comes from a file rather than a tty.  

The implementation of read_redirected() did not support lines longer
than 64 chars.  It tried to realloc(), but goofed up and instead
truncated all the first 64 chars.  The result was that each read
line only contained the reminder of a a division with 64... :-)
