Bug#773362: iwyu: does not handle the -- in the options correctly

[Paul Wise]

Package: iwyu
Version: 3.4-1
Severity: normal
Usertags: arg-injection

include-what-you-use does not handle -- in the options correctly. Using
-- just causes an error but it should signal the end of the options so
that filenames starting with -- are not interpreted as options.

pabs at chianamo ~ $ include-what-you-use main.c 
main.c:12:10: fatal error: 'net/mac80211.h' file not found
#include <net/mac80211.h>
         ^

main.c should add these lines:

main.c should remove these lines:
- #include <linux/if_arp.h>  // lines 20-20
- #include <linux/netdevice.h>  // lines 15-15
- #include <linux/rtnetlink.h>  // lines 21-21
- #include <linux/types.h>  // lines 16-16
- struct ieee80211_txrx_stypes;  // lines 381-381
