Update the logic to compute the display width needed for utf8

We used to unconditionally disable the pager in the pager process
we spawn to feed out output, but that prevented people who want to
run "less" within "less" from doing so.

Since the very beginning of Git, we gave the LESS environment a
default value "FRSX" when we spawn "less" as the pager.  "S" (chop
long lines instead of wrapping) has been removed from this default
set of options, because it is more or less a personal taste thing,
as opposed to others that have good justifications (i.e. "R" is very
much justified because many kinds of output we produce are colored
and "FX" is justified because output we produce is often shorter
than a page).

Existing users who prefer not to see line-wrapped output may want to
set

  $ git config core.pager "less -S"

to restore the traditional behaviour.  It is expected that people
find output from the most subcommands easier to read with the new
default, except for "blame" which tends to produce really long
lines.  To override the new default only for "git blame", you can do
this:

  $ git config pager.blame "less -S"

* mm/pager-less-sans-S:
  pager: remove 'S' from $LESS by default

Running "git update-index --cacheinfo" without any further
arguments results in a segfault rather than an error
message. Commit ec160ae1 (update-index: teach --cacheinfo a
new syntax "mode,sha1,path", 2014-03-23) added code to
examine the format of the argument, but forgot to handle the
NULL case.

Returning an error from the parser is enough, since we then
treat it as an old-style "--cacheinfo <mode> <sha1> <path>",
and complain that we have less than 3 arguments to read.
