It should be more reliable than parsing a command string into array.
Also updated some of the doc example to use array syntax. I don't think
"C:/Program Files" was parsed properly, but might work thanks to Windows
magic.
It implements Deserialize because config.get() requires that. We could instead
add TryFrom<config::Value>, but we'll need Deserialize anyway if we want to
parse a struct containing FullCommandArgs.
I don't know if src/config.rs is the right place, but I feel it's slightly
better than messing up ui.rs.
Teach Ui's writing functions to write to a pager without touching the
process's file descriptors. This is done by introducing UiOutput::Paged,
which spawns a pager that Ui's functions can write to.
The pager program can be chosen via `ui.pager`. (defaults to Defaults to
$PAGER, and 'less' if that is unset (falling back to 'less' also makes
the tests pass).
Currently, commands are paginated if:
- they have "long" output (as defined by jj developers)
- jj is invoked in a terminal
The next commit will allow pagination to be turned off via a CLI option.
More complex pagination toggling (e.g. showing a pager even if the
output doesn't look like a terminal, using a pager for shorter ouput) is
left for a future PR.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).

It would be nice to be able to use snapshot testing and not have to
parse the output of `jj op log`. This patch lets us do that by
providing a new environment variable and config for overriding the
timestamps. Unlike `operation.hostname` and `operation.username`,
these are only meant for tests.
This makes the tests more hermetic, even though I don't think the
default values (taken from `whoami`) can break any tests (then we
would have already seen them break). Now we just need to make the
operation log's timestamps predictable and then we can start using
operation IDs in snapshot tests.
According to the NO_COLOR FAQ, "user-level configuration files [...] should
override $NO_COLOR." https://no-color.org/
Unfortunately this makes it harder to test the $NO_COLOR behavior since the
test environment isn't attached to a tty. We could allocate a pty or
LD_PRELOAD shim to intercept isatty(), but I feel it would be too much to do.

With this patch, the order is this:
`$JJ_EDITOR` environement variable
`ui.editor` config
`$VISUAL` environement variable
`$EDITOR` environement variable
`pico`
That matches git, except that git falls back to an editor determined
at compile time (usually `vi`) instead of using `pico`.
As I said in 095fb9fef4, removing support for `~/.jjconfig` was an
experiment. I've heard from a few people (including in #233) that they
would prefer to have configs in the home directory. This patch
therefore restores that functionality, except I added a `.toml`
extension to the file to clarify the expected format to users and
editors.
After this patch, we still allow configs in `$XDG_CONFIG_HOME` (and
the other paths used by `dirs::config_dir()`), but we error out there
are config files in both that location and `~/.jjconfig.toml`.
