tests: unset COLUMNS inherited from environment

$COLUMNS must be unset to not interfere with the tests. The tests
already ignore the terminal size because output is redirected to a
file, but COLUMNS overrides terminal size detection and changes the
test output away from the standard 80.

correct a few doubled-word nits in comments and documentation

Found by running this command:
$ git ls-files -z|xargs -0 perl -0777 -n \
 -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt]o)\s+\1\b/gims)' \
 -e '  {' \
 -e '    $n = ($` =~ tr/\n/\n/ + 1);' \
 -e '    ($v = $&) =~ s/\n/\\n/g;' \
 -e '    print "$ARGV:$n:$v\n";' \
 -e '  }'

Why not just git grep -E ...?
That wouldn't work then the doubled words are separated by a newline.
This is derived from a Makefile syntax-check rule in gnulib's maint.mk:

config: remove useless assignment

v1.7.9-8-g270a344 (config: stop using config_exclusive_filename) replaced
config_exclusive_filename with given_config_file.  In one case this
resulted in a self-assignment, which is reported by clang as a warning.
Remove the useless code.

gitk: fix tabbed preferences construction when using tcl 8.4

In 8.5 the incr command creates the target variable if it does not exist
but in 8.4 using incr on a non-existing variable raises an error. Ensure
we have created our counter variable when creating the tabbed dialog for
non-themed preferences.
