[patch] maintain output column


From: Thien-Thi Nguyen
Subject: [patch] maintain output column
Date: Tue, 13 Nov 2007 15:17:40 +0100

before, we see:
(guile-user) (port-column (current-output-port))
13

after, we see:
(guile-user) (port-column (current-output-port))
0

here is the ChangeLog entry for guile 1.4.x:

2007-11-13  Thien-Thi Nguyen  <address@hidden>

        * running-repls.scm (scm-style-repl consume-trailing-whitespace):
        On #\newline, zero the output port's column.

i'm sure you can figure out where this would fit for other versions.
