`exec` now exhibits the same behavior as `exit` and prompts the user to
confirm their intention to end the current process if there are
background jobs running. Running `exec` again immediately thereafter
will force the exec to go through.
Additionally, background jobs are reaped upon exec to prevent process
leaking (same as `exit`).
- Add support for:
- Jumping to the character before a target.
- Repeating the previous jump (same direction, same precision).
- Repeating the previous jump in the reverse order.
- Enhance vi bindings.
Factor the history search fields into a new class.
As a side effect, this shares the deduplication logic, so that token search
no longer returns duplicates.

While supported by gcc and clang, \e is a gcc-specific extension and not
formally defined in the C or C++ standards.
See [0] for a list of valid escapes.

The prompt is a fallback that is overridden via a function file
anyway.
Do that with the title as well, so we can use just builtins.
This removes error messages when $fish_function_path is borked.
This allows prompts to react to $COLUMNS by e.g. omitting some parts.
We still fallback to a ">" prompt if that's still not short enough,
but now the user has a way of making a nicer prompt.
Fixes#904.
Fixes#4381.
Properly escape literal tildes in tab completion results. Currently we
always escape tildes in unquoted arguments; in the future we may escape
only leading tildes.
Fixes#2274
When the pager wants to use the full screen to show many options, it reserves
space at the top to see the command. Previously it pretended the command was a
prompt and engaged the prompt layout mechanism to compute these lines. Instead
let's juts count newlines since escape sequences within commands are very rare.
Prior to this fix, if the user typed normal characters while the
completion pager was shown, it would begin searching. This feature was
not well liked, so we are going to instead just append the characters as
normal and disable paging. Control-S can be used to toggle the search
field.
Fixes#2249
As discussed in #3805, this patch disables assigning fish to its own
process group at startup. This was trialled in #4349 alongside other
pgrp fixes which introduced additional problems, but this particular fix
seems to be OK.
Fixes#3805 and works around Microsoft/BashOnWindows#1653
This eliminates the "missing" notion of env_var_t. Instead
env_get returns a maybe_t<env_var_t>, which forces callers to
handle the possibility that the variable is missing.
Internally fish should store vars as a vector of elements. The current
flat string representation is a holdover from when the code was written
in C.
Fixes#4200
