In the older days, the header "Conflicts:" in "cherry-pick" and
"merge" was separated by a blank line from the list of paths that
follow for readability, but when "merge" was rewritten in C, we lost
it by mistake. Remove the newline from "cherry-pick" to make them
match again.

The filesystem boundary was not correctly reported when .git directory
discovery stopped at a mount point.

By Clemens Buchacher
* cb/maint-report-mount-point-correctly-in-setup:
  properly keep track of current working directory

The command line parser choked "git cherry-pick $name" when $name can be
both revision name and a pathname, even though $name can never be a path
in the context of the command.

The issue the patch addresses is real, but the way it is implemented felt
unnecessarily invasive a bit.  It may be cleaner for this caller to add
the "--" to the end of the argv_array it passes to setup_revisions().

Fixes http authentication breakage when we keep multiple HTTP requests in
flight using curl-multi.

  http: use newer curl options for setting credentials

On Linux, this makes authentication using passwords from gnome-keyring

using the OS X Keychain.

The 'push to upstream' implementation was broken in some corner

"git clean -d -f" (not "-d -f -f") is supposed to protect nested

After running rev-list --boundary to retrieve the list of boundary
commits, "git bundle create" runs its own revision walk.  If in this
stage git encounters an unfamiliar option, it writes a message with an
unbalanced quotation mark:

	error: unrecognized argument: --foo'

Drop the stray quote to match the "unrecognized argument: %s" message
used elsewhere and save translators some work.

This is mostly a futureproofing measure: for now, the "rev-list
--boundary" command catches most strange arguments on its own and the
above message is not seen unless you try something esoteric like "git
bundle create test.bundle --header HEAD".
