da7b762f4a Make default hg prompt leaner 
The default hg prompt is slow on large repositories (hg status takes
2-3 seconds on mozilla-central) which is unacceptable as a default.

Mimick our git prompt: by default, only show the current branch.
If the new variable $fish_prompt_hg_show_informative_status is set,
then use the old behavior.

bfc1de9ef4 argparse: Pass validation variables as exported 
This was written before local-exported variables did anything useful.

Passing these vars as local-exports removes the need to define the
validation function with `--no-scope-shadowing` which is quite the
hack.

0f34459fce Disable svn prompt by default 
This is apparently quite slow on large svn repos (like 40 seconds
slow), and we don't have a good thing to display other than the full
file information.

So we'll have to disable it for now.

Fixes #6681.

b5cbdc623d docs/tutorial: Replace coloring markup 
This used to use doxygen's html blocks, which don't have a *direct*
equivalent in sphinx in code blocks.

Instead of adding this to the pygments highlighter, let's just use
some roles.

It's a teensy bit awkward as we then use block styling, but we want to
add more of our own styling anyway, so we can presumably get this
somehow, and these html tags look awkward and confuse people.

Fix #6640

300ms was waaay too long, and even 100ms wasn't necessary.

raise the timeout.

selected, and when a row is secondary. More specifically this commit adds the
ability to specify a pager row's:

- Prefix
- Completion text
- Description
- Background

when said row is selected or secondary.

1d5e715008 source: Return error instead of implicitly reading from tty

3f3b3a7006 Export arrays as colon delimited, and support path-style variables 
This commit begins to bake in a notion of path-style variables.

Prior to this fix, fish would export arrays as ASCII record separator
delimited, except for a whitelist (PATH, CDPATH, MANPATH). This is
surprising and awkward for other programs to deal with, and there's no way
to get similar behavior for other variables like GOPATH or LD_LIBRARY_PATH.

This commit does the following:

1. Exports all arrays as colon delimited strings, instead of RS.

2. Introduces a notion of "path variable." A path variable will be
"colon-delimited" which means it gets colon-separated in quoted expansion,
and automatically splits on colons. In this commit we only do the exporting
part.

Colons are not escaped in exporting; this is deliberate to support uses
like

    `set -x PYTHONPATH "/foo:/bar"`

which ought to work (and already do, we don't want  to make a compat break
here).

0f0bb1e10f Don't resolve symlinks with cd 
This switches fish to a "virtual" PWD, where it no longer uses getcwd to
discover its PWD but instead synthesizes it based on normalizing cd against
the $PWD variable.

Both pwd and $PWD contain the virtual path. pwd is taught about -P to
return the physical path, and -L the logical path (which is the default).

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.

(faho: Remove bare "self")

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.
