Add two new functions, string_list_split() and
string_list_split_in_place().  These split a string into a string_list
on a separator character.  The first makes copies of the substrings
(leaving the input string untouched) and the second splits the
original string in place, overwriting the separator characters with
NULs and referring to the original string's memory.

These functions are similar to the strbuf_split_*() functions except
that they work with the more powerful string_list interface.

Add a new function that appends a string to a string_list without
copying it.  This can be used to pass ownership of an already-copied
string to a string_list that has strdup_strings set.

Output from "git branch -v" contains "(no branch)" that could be
localized, but the code to align it along with the names of branches
were counting in bytes, not in display columns.

* nd/branch-v-alignment:
  branch -v: align even when branch names are in UTF-8

Pushing to smart HTTP server with recent Git fails without having
the username in the URL to force authentication, if the server is
configured to allow GET anonymously, while requiring authentication
for POST.

The synopsis said "checkout [-B branch]" to make it clear the branch
name is a parameter to the option, but the heading for the option
description was "-B::", not "-B branch::", making the documentation
misleading.  There may be room in documentation pages of other
commands for similar improvements.

* jc/maint-doc-checkout-b-always-takes-branch-name:
  doc: "git checkout -b/-B/--orphan" always takes a branch name

"git apply -p0" did not parse pathnames on "diff --git" line
correctly.  This caused patches that had pathnames in no other
places to be mistakenly rejected (most notably, binary patch that
does not rename nor change mode).  Textual patches, renames or
mode changes have preimage and postimage pathnames in different
places in a form that can be parsed unambiguously and did not suffer
from this problem.

* jc/apply-binary-p0:
  apply: compute patch->def_name correctly under -p0

"git log .." errored out saying it is both rev range and a path when
there is no disambiguating "--" is on the command line.  Update the
command line parser to interpret ".." as a path in such a case.

"git submodule update --force" used to leave the working tree of the
submodule intact when there were local changes.  It is more intiutive
to make "--force" a sign to run "checkout -f" to overwrite them.

"git stash" internally used "git merge-recursive" backend, which did
