This makes two changes:
1. Remove the 'brace_text_start' idea. The idea of 'brace_text_start' was
to prevent emitting `BRACE_SPACE` at the beginning or end of an item. But
we later strip these off anyways, so there is no apparent benefit. If we
are not doing brace expansion, this prevented emitting whitespace at the
beginning or end of an item, leading to #6564.
2. When performing brace expansion, only stomp the space character with
`BRACE_SPACE`; do not stomp newlines and tabs. This is because the fix in
came from a newline or tab literal, then we would have effectively
replaced a newline or tab with a space, so this is important for #6564 as
well. Moreover, it is not easy to place a literal newline or tab inside a
brace expansion, and users who do probably do not mean for it to be
stripped, so I believe this is a good change in general.
Fixes#6564
fish has some unprincipled code that attempts to tcsetpgrp() to own the
terminal before running a builtin; this was added because 'read' might
want to read from the terminal. I added this code before fully
understanding how process groups and terminals work. A better fix would
be to ensure that fish is marked as the pgroup leader in the job when
the builtin is the first process in the job, and we do that now.
Courageously back out the changes to grab the terminal; see #5147 and
also #5133.
Just another version of the error. We still want to get a bug if it
ever triggers a *wrong* error, so we still list all the options
instead of going for `.*option:.*Z.*`.

Solaris/OpenIndiana/Illumos `rm` checks that and errors out.
In these cases we don't actually need it to be a part of $PWD as
it's just for cleanup, so we `cd` out before.

Introduce pgroup_provenance_t, a type which captures "where the pgroup
comes from." This centralizes some logic around how pgroups are
assigned, and it anticipates concurrent execution.

In some cases on some platforms this could clobber errno, so doing something like
aThingThatFailsWithErrno();
FLOG(category, "Some message");
wperror("something");
would print the wrong error (presumably if that category was enabled).
In our case it was our (very) old friend RHEL6 returning ESPIPE instead of EISDIR.
Fixes#6545.
At the moment the "prepend sudo" functionality always sets the cursor to
the end of the line. This changes it to restore the relative position of
the cursor.
Prior to this fix, the cancellation C++ test would mark the parser as
interactive in an effort to install interactive signal handling (so that,
for example, SIGINT would stop the job and return control to the user).
However this flag would also cause fish to attempt to save and restore tty modes
across the job. This would fail since there is no tty, and so the job would fail
with an unexpected error code.
We don't need to mark the parser as interactive, we can just remove that line.
Fixes#6539.
