[lvm-devel] LVM2/lib/report columns.h report.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2010-08-20 12:44:17

Modified files:
	lib/report     : columns.h report.c 

Log message:
	Remove explicit double quotes from columns.h 'id' entries.
	
	The 'id' entries in columns.h are the report field names.  Since these are
	unique, we'd like to use them in generation of 'get' / 'set' functions.
	As a step towards using them for this purpose, remove the explicit double
	quotes and use the macro '#' character to add the double quotes back when
	placing them into the '_fields' array 'id' member.
