Hello,
If patch 2/2 is approved, I'd like to apply this alongside with that.
Use positive form ("suppress") rather than negative ("don't") to explain
the option, because using the option results in passing -Wno-format
rather than not passing -Wformat. I felt confused when trying to follow
the logic of the option, and this change would clarify things for me.
Unpaired apostrophe in "don't" also happens to break syntax matching in Vim.
* configure.ac (build-format-warnings): Reword help text.
* configure: Regenerate.
