[PATCH] More readable 'Not a git repository' messages

[Ralf Ebert <info@ralfebert.de>]

Stating the folder concerned with the operation and wording the
messages differently make them slightly more readable.

old: Not a git repository (or any of the parent directories): .git
new: Not in a git repository: /home/bob/somefolder

old: Not a git repository (or any parent up to mount parent /home/bob)
old: Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM 
not set).
new: Not in a git repository: /home/bob/somefolder
new: (stopped searching at /home because GIT_DISCOVERY_ACROSS_FILESYSTEM 
is not set)
