Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.

eval "("
echo $status
Rationalize $status and errors Prior to this fix, fish was rather inconsistent in when $status gets set in response to an error. For example, a failed expansion like "$foo[" would not modify $status. This makes the following inter-related changes: 1. String expansion now directly returns the value to set for $status on error. The value is always used. 2. parser_t::eval() now directly returns the proc_status_t, which cleans up a lot of call sites. 3. We expose a new function exec_subshell_for_expand() which ignores $status but returns errors specifically related to subshell expansion. 4. We reify the notion of "expansion breaking" errors. These include command-not-found, expand syntax errors, and others. The upshot is we are more consistent about always setting $status on errors.

# CHECK: 123
eval tests: Fix path I tested this manually (`littlecheck.py -s fish=fish tests/checks/eval.fish`) from the base directory, which means I got "tests/checks/eval", while the real test gets "checks/eval". I then reran `make test_fishscript`, but that didn't pull in the updated test - we should really handle that better.

source: Escape filenames in errors Otherwise this would look weird if you had, say, a tab in there. See #7716. (note that this doesn't handle e.g. zero-width-joiners, because those aren't currently escaped. we might want to add an escape mode for unprintable characters, but for combining codepoints that's tricky!)
