Re: [patch] fixes numerous glib faults and mistypes, also re-whitespaced

(Note this e-mail being forwarded to the GTK+ app devel list, anyone who
has any idea on what might cause this glib behavour please reply!)


Erf, goodness!  This is really awkward.

I have a hunch, what if instead, you reverted back to the original source

whatever its equiv is?)

For everyone else the source for this GTK+ app in question is at:

        ftp://fox.mit.edu/pub/xsw/manedit0.4.tgz
