I've took a look and fixed some warnings around and other small stuff.
They are consts, a little uint vs. int when I'm sure it makes sense,
staticize a few local functions, and so on.

I've found 4 things that I haven't fixed/touched:
* build.c:174: This type of assignations aren't valid C90 (it's a C99
addition I think). Not sure it should be fixed or not since it gives a
little gain - being sure the affected element is the right one.
* document.c:473: The function document_stop_file_monitoring() has no
prototype and isn't static, but the name made me think it is perhaps
meant to be external for some reason and only misses its prototype?
* main.c:1212+: What's that malloc stuff for??? These functions aren't
even used...
* the stash_group_add_entry() and its widget_id. The thing is that when
it is a string it should be constant, but when it is a widget it
shouldn't be... perhaps it is fine as now.

There is 2 patches: one that modifies the Geany's core, and the other
that modifies that core plugins [1].

Colomban

[1] there is a missing free() fix for the export plugin too.
