- In many cases, using QLatin1String is a de-optimization, when
applied to a C string literal. Kevin Kofler pointed out that
those should basically all be QStringLiteral, instead. (Compile
tests with -O3 show that in the optimized object file, the
code size difference is negligible).
- Drop the explicit constructor entirely in cases where we're calling
QProcess::execute(), for consistency.
- Do a little less messing around in the mapping of keyboard locales
to keyboard map names.
- In GeoIP handler constructors that take a string (to configure the
selector to use), interpret the empty string (which generally isn't
a meaningful selector) as meaning "use the default".
- Drop the no-argument constructors in favor of a default-argument
which is empty.
- GeoIP gets a string selector; the interpretation is up to derived classes.
- GeoIPXML and GeoIPJSON use the selector to select an element by tag
or an attribute, respectively.
