The color palette used by "git grep" has been updated to match that
of GNU grep.
* lh/use-gnu-color-in-grep:
grep: align default colors with GNU grep ones
git-grep shares a lot of options with the standard grep tool.
Like GNU grep, it has coloring options to highlight the matching text.
And like it, it has options to customize the various colored parts.
This patch updates the default git-grep colors to make them match the
GNU grep default ones [1].
It was possible to get the same result by setting the various `color.grep.<slot>`
options, but this patch makes `git grep --color` share the same color scheme as
`grep --color` by default without any user configuration.

315a84f9aa (subtree: use commits before rejoins for splits, 2018-09-28)
changed the signature of check_parents from 'check_parents [REV...]'
to 'check_parents PARENTS_EXPR INDENT'. In other words the variable list
of parent revisions became a list embedded in a string. However it
neglected to unpack the list again before sending it to cache_miss,
leading to incorrect calls whenever more than one parent was present.
This is the case whenever a merge commit is processed, with the end
result being a loss of performance from unecessary rechecks.
The indent parameter was subsequently removed in e9525a8a02 (subtree:
have $indent actually affect indentation, 2021-04-27), but the argument
handling bug remained.
For consistency, take multiple arguments in check_parents,
and pass all of them to cache_miss separately.

When in cone mode sparse-checkout, it is unclear how 'git
sparse-checkout add <dir1> ...' should behave if the existing
sparse-checkout file does not match the cone mode patterns. Change the
behavior to fail with an error message about the existing patterns.
Also, all cone mode patterns start with a '/' character, so add that
restriction. This is necessary for our example test 'cone mode: warn on
bad pattern', but also requires modifying the example sparse-checkout
file we use to test the warnings related to recognizing cone mode
patterns.
This error checking would cause a failure further down the test script
because of a test that adds non-cone mode patterns without cleaning them
up. Perform that cleanup as part of the test now.

Add a test to t1091-sparse-checkout-builtin.sh that would result in an
infinite loop and out-of-memory error before this change. The issue
relies on having non-cone-mode patterns while trying to modify the
patterns in cone-mode.
The fix is simple, allowing us to break from the loop when the input
path does not contain a slash, as the "dir" pattern we added does not.
This is only a fix to the critical out-of-memory error. A better
response to such a strange state will follow in a later change.

Then core.sparseCheckoutCone is enabled, the sparse-checkout patterns are
used to populate two hashsets that accelerate pattern matching. If the user
modifies the sparse-checkout file outside of the 'sparse-checkout' builtin,
then strange patterns can happen, triggering some error checks.
One of these error checks is possible to hit when some special characters
exist in a line. A warning message is correctly written to stderr, but then
there is additional logic that attempts to remove the line from the hashset
and free the data. This leads to a segfault in the 'git sparse-checkout
list' command because it iterates over the contents of the hashset, which is
now invalid.
The fix here is to stop trying to remove from the hashset. In addition,
we disable cone mode sparse-checkout because of the malformed data. This
results in the pattern-matching working with a possibly-slower
algorithm, but using the patterns as they are in the sparse-checkout
file.
This also changes the behavior of commands such as 'git sparse-checkout
list' because the output patterns will be the contents of the
sparse-checkout file instead of the list of directories. This is an
existing behavior for other types of bad patterns.
Add a test that triggers the segfault without the code change.

Many git commands that deal with working tree files try to remove a
directory that becomes empty (i.e. "git switch" from a branch that

remove all files in the directory and the directory itself). This
