Hi,

This is a speed-up patch. I converted a few loops from byte-per-byte
reading to block-per-block reading. Here's some numbers :

(GnuPG compiled with egcs 1.1.1 -O2 -m486 -g, timing done on a 486
dx4/100 under Linux 2.2.5, with a 14 MB .tar.bz file)

Symmetric encryption :
--------------------
CAST5 BLOWFISH 3DES

Symmetric decryption :
--------------------
CAST5 BLOWFISH 3DES
unpatched 1:55 1:58 2:38

Public-key encryption + signature : (2048-bit El-Gamal key)

Notes:
- the way I patched plaintext.c isn't very clean...
- in the THANKS file, you list me as 'rguyomarch@ifn.fr'. This is
my professional address and since I'm doing this in my spare time at
home, can you change it to 'rguyom@mail.dotcom.fr' ? Thanks.
