LANG=ru_RU.KOI8-R grep -i <some single KOI8-R letter>
Fix it.

bf70becee6 More -Wmissing-variable-declarations fixes. 
In addition to adding `static' where possible:

- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

f20f6f3fdf Update BSD grep to the latest development version. It has some code 
backported that was written for the TRE integration project in Google
Summer of Code 2011.  This is a temporary solution until the whole
regex library is not replaced so that BSD grep development can continue
and the backported code gets some review and testing.  This change only
improves scalability slightly, there is no big performance boost yet
but several minor bugs have been found and fixed.
