bda147c7d3 Correct math docs 
This was an oversight when math was changed to default to float output.

Also some more jokey stuff. Jokey stuff is nice.

81a987c39c Fix range expansion with negative ends 
If just one of the range ends is negative, this now forces direction away from it.

I.e. if the beginning is negative, we go in reverse.
If the end is negative, we go forwards.

This fixes cases like

    $var[2..-1]

if $var only has one element.

21890ccac7 function: restore '%self' functionality for --on-process-exit 
One key use of process expansion, used in currently-shipped code, is for running a function on
current shell exit.

Restore the use of %self as a valid argument (and add `self`) and document this change.

5282d3e711 Add fish_emoji_width variable to control computed emoji width 
This is part of an effort to improve fish's Unicode handling. This commit
attempts to grapple with the fact that, certain characters (principally
emoji) were considered to have a wcwidth of 1 in Unicode 8, but a width of
2 in Unicode 9.

The system wcwidth() here cannot be trusted; terminal emulators do not
respect it. iTerm2 even allows this to be set in preferences.

This commit introduces a new function is_width_2_in_Uni9_but_1_in_Uni8() to
detect characters of version-ambiguous width. For these characters, it
returns a width guessed based on the value of TERM_PROGRAM and
TERM_VERSION, defaulting to 1. This value can be overridden by setting the
value of a new variable fish_emoji_width (presumably either to 1 or 2).

Fixes #4539, #2652.
