[svn-commits] murf: trunk r81519 - in /trunk: include/asterisk/config.h main/config.c

New Revision: 81519

URL: http://svn.digium.com/view/asterisk?view=rev&rev=81519
Log:
this set of changes fixes issue # 10643 by keeping track of the last object defined in a file, and attaching any accumulated comments to that object (category header or variable declaration). The file_save routine also had to be upgraded to output these trailing comments. Config.h was modified to include the trailing comment list on categories and variables.
