Hi all.
I've just could not install shiftcolumn plugin from trunk on a clean system. In shiftcolumn.c sciwrappers.h is included, which is not installed since Geany r4366. The attached patch replaces includes in shiftcolumn.c with the single include file geanyplugin.h. After this change geany-plugins compiled successfully. The patch is against the latest trunk (that is, r1053).
Best regards, Eugene.
