Use C locale when parsing UseDelta floating point values
We should save the current locale, use the 'C' locale during parsing, then restore the original locale. Config files should always parse regardless of the current user's locale setting. Fixes FS#34253. Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
