The problem with file.c still persists when I enter the filename from
the command line and then "save to" via the gui. This is caused by the
file requester always returning an absolute path. I've created a very
preliminary patch that resolves this. I don't know whether this has any
chance of working with Windows too, or if I should put a #ifdef Unix
around the new code. Please let me know how to improve this patch. I'm
also planning to handle the error case differently: Create a temporary
file, write to that and after that unlink the old one and rename the
temp file. As this replaces Ethereal's input file, I guess I have to
take care of that. Is this more than closing and reopening the file?

I found out that "pro" means "instead of" (as in proconsul). Now I know
what proactive means.
