share: stop using 'islocal' with repo instance
Having this level of polymorphism of the `islocal` function is weird, and we
already have a way to know if the repo is local from the object itself.
We are about to deprecate passing a non-bytes object to `islocal`, so clean this
up beforehand.
We might want to clean up this function too in the future, however this is
another adventure.
$ hg init repo
$ cd repo
$ echo a > a
$ hg ci -Ama
adding a
$ hg an a
0: a
$ hg --config ui.strict=False an a
0: a
$ echo "[ui]" >> $HGRCPATH
$ echo "strict=True" >> $HGRCPATH
$ hg an a
hg: unknown command 'an'
(use 'hg help' for a list of commands)

$ hg annotate a
0: a
should succeed - up is an alias, not an abbreviation
$ hg up
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
