match: avoid rust fast path if the matcher was tampered with
Otherwise the fast path does not respect the modifications made
by the extension (concretely largefiles, but other extensions can
start using that too)
Same with share-safe
$ echo "[format]" >> $HGRCPATH
$ echo "use-share-safe = True" >> $HGRCPATH
$ cd $TESTTMP
$ hg init myrepo
$ cd myrepo
$ cat > .hg/hgrc <<EOF

$ echo a > show
$ echo x > hide
$ hg ci -Aqm 'initial'
Regression test: checks that this command correctly locks the store
before updating the store [requirements] config.
$ hg up -q 0
$ hg debugsparse --include 'hide'
