Less config

#
# less
#
# -F or --quit-if-one-screen
#       Causes less to automatically exit if the entire file can be displayed on the first screen.
#
# -i or --ignore-case
#   Causes searches to ignore case; that is, uppercase and lowercase are
#   considered identical.  This option is ignored if any uppercase letters
#   appear in the search pattern; in other words, if a pattern contains
#   uppercase letters, then that search does not ignore case.
#
# -S or --chop-long-lines
#   Causes lines longer than the screen width to be chopped (truncated) rather
#   than wrapped.  That is, the portion of a long line that does not fit in the
#   screen width is not shown.  The default is to wrap long lines; that is,
#   display the remainder on the next line.
#
# -R or --RAW-CONTROL-CHARS
#   Like -r, but only ANSI "color" escape sequences are output in "raw" form.
#   Unlike -r, the screen appearance is  maintained correctly in most cases.
#   ANSI "color" escape sequences are sequences of the form:
#
#       ESC [ ... m
#
#   where the "..." is zero or more color specification characters For the
#   purpose of keeping track of screen appearance, ANSI color escape sequences
#   are assumed to not move the cursor.  You can make less think that characters
#   other than "m" can end ANSI color escape sequences by setting the
#   environment variable LESSANSIENDCHARS to the list of characters which can
#   end a color escape sequence.  And you can make less think that characters
#   other than the standard ones may appear between the ESC and the m by setting
#   the environment variable LESSANSIMIDCHARS to the list of characters which
#   can appear.
#
# -X or --no-init
#       Disables sending the termcap initialization and deinitialization strings
#       to the terminal.  This is sometimes desirable  if the deinitialization
#       string does something unnecessary, like clearing the screen.
#
# -xn,... or --tabs=n,...
#   Sets tab stops.  If only one n is specified, tab stops are set at multiples
#   of n.  If multiple values separated by commas are specified, tab stops are
#   set at those positions, and then continue with the same spacing as the last
#   two.  For example, -x9,17 will set tabs at positions 9, 17, 25, 33, etc.
#   The default for n is 8.
#
# -# or --shift
#   Specifies the default number of positions to scroll horizontally in the
#   RIGHTARROW and LEFTARROW commands.  If the number specified is zero, it sets
#   the default number of positions to one half of the screen width.
#   Alternately, the number may be specified as a fraction of the width of the
#   screen, starting with a decimal point: .5 is half of the screen width, .3 is
#   three tenths of the screen width, and so on.  If the number is specified as
#   a fraction, the actual number of scroll positions is recalculated if the
#   terminal window is resized, so that the actual scroll remains at the
#   specified fraction of the screen width.
#

# Notes:
#
# We use the --raw-control-chars option because `git diff` breaks otherwise.
