Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

* Historical whackadoo. The dot command `puts' the numbered buffer
* after the last one put. For example, `"4p.' would put buffer #4
* and buffer #5. If the user continued to enter '.', the #9 buffer
* would be repeatedly output. This was not documented, and is a bit
* tricky to reconstruct. Historical versions of vi also dropped the
* contents of the default buffer after each put, so after `"4p' the
* default buffer would be empty. This makes no sense to me, so we
* don't bother. Don't assume sequential order of numeric characters.
*
* And, if that weren't exciting enough, failed commands don't normally
* set the dot command. Well, boys and girls, an exception is that
* the buffer increment gets done regardless of the success of the put.
