... and deduce whether to exclude from macros inside NewIdentifier, simplifying
argument lists further
Also fix the localization of "..." added to names by PluginMenus.cpp
... The purpose of the boolean field in command entries was to exclude certain
menu commands from being steps in macros, because they require user interaction.
Effects are never meant to be excluded, even though they normally have dialogs,
but in the context of macro execution, the parameters are supplied by other
means.
... This capability was unused. The only uses of item lists are in
TrackMenus.cpp, for aligning tracks.
The parsing of a translated string for encoded infomration was questionable.
... This could only affect the About dialog now, but does not have noticeable
effects.
StartNotebookPage will be reused for Export and Export Multiple dialogs, and
the effects of this SetMinSize call would be undesirable for them.
... Format arguments are substituted into the translation of the msgid, which
may not be known at the time the format arguments are captured (because locale
may change). This allows TranslatableString with arguments to be constructed
at static initialization time.
There is also a special "verbatim" or null context which makes no translations
of msgids.
There is not yet any use of other contexts besides default or null.
... include it in the msgid intead, to get appropriate translations. For
instance some locales use the same character but prefer to insert a space
before it.
... And corrected improper connections in HistoryWindow and ContrastDialog,
improper because they got called with the wrong this pointer, to
the control instead of the dialog. But that was harmless anyway because the
handlers did not use this.
... This type is now the value returned by the XO macro, and holds a string
that should be looked up in the translation catalog, not shown directly to the
user.
The type does not implicitly convert to or from wxString, so you must construct
it explicitly, or use XO, or use its Translation() member function, or else the
compiler stops you with an error.
