Only enable submit button in the git submit editor when a non-empty
desciption of the patch is available. Git rejects empty commit messages
and old versions fail without even giving an error Qt Creator can detect,
so this should make commiting a bit more save.

Do not offer to commit in the dialog opened when closing the

Handle shadowed variables and __formal parameters. Differentiate
between name and iname in SymbolGroup.

 * Warn on spaces in the project path
 * Warn on special characters in the project name only

Always nice to know which part failed.

Preparing the introduction of tooltips for the new
CDB engine. Fix some breakpoint states in CDB.

QFontMetricsF::averageCharWidth seems to always return a fractional size
(at least on Linux/GNOME with DejaVu Mono), even when the font is not
actually drawn at sub-pixels. This caused the visible wrap column to
appear in the wrong place.

As a workaround, use the width of the character 'x', which is pretty
average and does align to pixels when needed.
