[patch, committed] invoke.texi: DWARF, stabs, and ELF

[Sandra Loosemore <sandra@codesourcery.com>]

[-- Attachment #1: Type: text/plain, Size: 626 bytes --]

Per the DWARF web site

http://dwarfstd.org/Download.php

the correct names of the various versions of the DWARF standard appear 
to be either "DWARF Version N" or "DWARF N", rather than e.g. "DWARF2", 
"DWARF-2", "dwarf2", or whatever.  This patch to invoke.texi makes usages 
reflect the official names.  Similarly, I've fixed up a couple instances 
of incorrect usage of "stabs" (official name seems to be all lowercase, 
like that) and "ELF".

Checked in to trunk as obvious.
