wm and tw cause formatting problem

In insert mode, if a line starts with "-" the next line is indented. This is
not what I want.

After a lot of experimenting, I found that it was because either
textwidth or wrapmargin was set to a non-zero value. Is there any way to
get round this? I do need to set textwidth but I don't want to have to
keep correcting lines with initial "-".
