20b909215d Note that the manual page of less(1) says:
Note  that  a preprocessor cannot output an empty file, since that
  is interpreted as meaning there is no replacement, and the  origi-
  nal file is used.  To avoid this, if LESSOPEN starts with two ver-
  tical bars, the exit status of the script becomes meaningful.   If
  the  exit  status is zero, the output is considered to be replace-
  ment text, even if it empty.  If the exit status is  nonzero,  any
  output  is ignored and the original file is used.  For compatibil-
  ity with previous versions of less, if LESSOPEN starts  with  only
  one vertical bar, the exit status of the preprocessor is ignored.

Use two pipe symbols for zless, so that zless'ing a compressed empty
file will give output rather than being interpreted as its compressed
form, which is typically a binary.

Thanks Mark Nudelman for pointing out this difference and the
suggested solution.

a1420f2d09 Update less to v436. This is considered as a bugfix release from vendor.
Major changes from v429:
 * Don't pass "-" to non-pipe LESSOPEN unless it starts with "-".
 * Allow a fraction as the argument to the -# (--shift) option.
 * Fix highlight bug when underlined/overstruck text matches at end of line.
 * Fix non-regex searches with ctrl-R.

5ffbf296e8 In rev. 1.2 we have introduced a fallback handler for files with unknown
extensions.  This seems to be unnecessary and prevents less(1) from being
able to detect file changes, so remove the part.

d975010767 Correct the script name to be "zless.sh". This avoids an extra cp/chmod
(from the sys.mk rule) while still installing it under the "zless" name.

b51b7d4a0f Add a zless script which invokes less using the lesspipe script. This is
similar to the zmore script that comes with gzip (and in fact, in most
Linux distros, zless is a symlink to that very same zmore script) but has
the advantage that you get the correct file name on the less status line,
and can use :n and :p to navigate back and forth between multiple files.

P.S. it is stupid I have to define both SCRIPTS and SCRIPTSNAME.
