Hi,
I imagine this is pretty obscure but I have hit it a couple of times
this last week. If your fileformats string initial entry is different
to the fileformat default value then doing :bwipeout on the last buffer
results in the new buffer using the default fileformat and not the first
format from fileformats. Follow? Try the following on Windows:
> vim -u NONE -U NONE --cmd 'set ffs=unix' -c 'set ff? | bw | set ff?'
Prefer Unix? This shows the same effect:
$ vim -u NONE -U NONE --cmd 'set ffs=dos' -c 'set ff? | bw | set ff?'
You should see the fileformat change across the bwipeout.
Attached is a patch that sets the new buffer's fileformat from an
existing fileformats in buf_copy_options() or the global default
fileformat if ffs is not set. It Works For Me(TM) but I don't know if
the side effects in set_fileformat() cause problems when called from
buf_copy_options().
HTH - TTFN
