[nedit-bw.git] / PrevOpenIgnoreMask.patch

From: Andrew Hood <ajhood@fl.net.au>
Subject: tmp-files in 'Open Previous'

This adds nedit.prevOpenFilesMask to the list of items which can be added to
.Xdefaults to enable you to stop files being added to the 'Open Previous'
menu. It also cleans up any files which have already made it into the list.

E.g.:

        nedit.prevOpenFilesMask: /tmp/junk/

The patch to doc/help.etx is included but not the files which would be
generated from it.

Original from here:

        http://sourceforge.net/tracker/index.php?func=detail&aid=506324&group_id=11005&atid=311005
        [ 506324 ] tmp-files in 'Open Previous'

Than integrated into this mess:

        http://sourceforge.net/tracker/index.php?func=detail&aid=1058246&group_id=11005&atid=311005
        [ 1058246 ] Patch Collection

2008-02-21 Bert Wesarg

        slightly extended and renamed to nedit.prevOpenIgnorePattern
