Subject: rev-parse doc: pass "--" to rev-parse in the --prefix example
X-Git-Tag: v2.12.0-rc0~60^2~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=11873b438faa13ff1416741bb48dbdaa8a6cc083;p=git

rev-parse doc: pass "--" to rev-parse in the --prefix example

The "--" argument avoids "ambiguous argument: unknown revision or
path not in the working tree" errors when a pathname argument refers
to a non-existent file.

The "--" passed explicitly to set was removed because rev-parse
outputs the "--" argument that it is given.
