- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Correct syntax error, remove the unescaped newline between "||" and the
command it is intended to test. pdksh and bash caught this syntax error,
sh(1) did not behave as intended.

PR: 40386

Only got one of the Perl usages.

Replace a perl usage with an AWK one.

Submitted by: Bob Willcox <bob@immure.com>

Use mktemp(1) for tempfiles (concatdb.sh), and increase the number of X's.

$Id$ -> $FreeBSD$

Set TMPDIR to /tmp
Remove the temp directory in trap.
Replace the buggy awk script with a correct perl script.

Don't make a copy of the input data anymore if the input is already
sorted (option -presort). This scheme avoid large temporary files in
/tmp.

Change default temporary directory (TMPDIR) from /tmp to /var/tmp.

Mosts users seems to have a larger /var/tmp partition
than /tmp - IMHO silly but who cares?

Improve shell variable substitution.

Allow TMPDIR to be set and actually *used*; if it not set, it defaults
to /tmp.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

bigram
Bigram does not remove newline at end of filename. This
break particulary the bigram algorithm and /var/db/locate.database
grow up 15 %.

Bigram does not check for characters outside 32-127.

The bigram output is silly and need ~1/2 CPU time of
database rebuilding.

old:
locate.bigram < $filelist | sort | uniq -c | sort -nr
^^^^^^^^^^^^^^
this can easy made bigram

new:
bigram < $filelist | sort -nr

code
Code does not check for char 31.
Use a lookup array instead a function. 3 x faster.

rewritten
