The regex update fixes the Rust nightly build failure by in turn updating
its simd dependency to 2.x.
The regex update also includes a literal optimization that uses Tuned
Boyer Moore.

clippy: fix a few lints
The fixes are:
* Use single quotes for single-character
* Use ticks in documentation when necessary.
* Just bow to clippy's wisdom.
Fixes#717 (partially)
The previous implementation of the smart-case feature was actually *too* smart,
in that it inspected the final character ranges in the AST to determine if the
pattern contained upper-case characters. This meant that patterns like `foo\w`
would not be handled case-insensitively, since `\w` includes the range of
upper-case characters A–Z.
As a medium-term solution to this problem, we now inspect the input pattern
itself for upper-case characters, ignoring any that immediately follow a `\`.
This neatly handles all of the most basic cases like `\w`, `\S`, and `É`, though
it still has problems with more complex features like `\p{Ll}`. Handling those
correctly will require improvements to the AST.
When processing a rule that ends in a slash, we strip it off and set the
`is_only_dir` flag. We then apply the rule that paths that aren't
absolute should be given an implicit `**/` prefix, while avoiding
adding that prefix if it already exists.
However, this means that we miss the case in which we had already
stripped off the trailing slash and set `is_only_dir`. Correct this
by also explicitly checking for that case.
Fixes#649
This optimization wasn't tested too carefully, and it seems to result
in a massive amount of file handles open simultaneously. This is likely
a result of the parallel iterator, where many directories are being
traversed simultaneously.
Fixes#648
This commit fixes the symlink loop checker in the parallel directory
traverser to open fewer handles at the expense of keeping handles held
open longer.
This roughly matches the corresponding change in walkdir:
