DESCRIPTION
-----------
option forces paths to be output relative to the project
top directory.
+--abbrev[=<n>]::
+ Instead of showing the full 40-byte hexadecimal object

+ Non default number of digits can be specified with --abbrev=<n>.
+
--::
Do not interpret any more arguments as options.
SYNOPSIS

DESCRIPTION
-----------
--name-status::
List only filenames (instead of the "long" output), one per line.
+--abbrev[=<n>]::
+ Instead of showing the full 40-byte hexadecimal object
+ lines, show only handful hexdigits prefix.
+ Non default number of digits can be specified with --abbrev=<n>.
+
paths::
When paths are given, show them (note that this isn't really raw
pathnames, but rather a list of patterns to match). Otherwise
