"git gui" l10n to Portuguese.

* va/git-gui-i18n:
  git-gui: l10n: add Portuguese translation
  git-gui i18n: mark strings for translation

The original command line syntax for "git merge", which was "git
merge <msg> HEAD <parent>...", has been deprecated for quite some
time, and "git gui" was the last in-tree user of the syntax.  This
is finally fixed, so that we can move forward with the deprecation.

* rs/git-gui-use-modern-git-merge-syntax:
  git-gui: stop using deprecated merge syntax

* 'va/i18n' of ../git-gui:
  git-gui: l10n: add Portuguese translation
  git-gui i18n: mark strings for translation

* 'rs/use-modern-git-merge-syntax' of git-gui:
  git-gui: stop using deprecated merge syntax

"git commit-tree" stopped reading commit.gpgsign configuration
variable that was meant for Porcelain "git commit" in Git 2.9; we
forgot to update "git gui" to look at the configuration to match
this change.

* js/git-gui-commit-gpgsign:
  git-gui: respect commit.gpgsign again

* 'js/commit-gpgsign' of ../git-gui:
  git-gui: respect commit.gpgsign again

* 'sy/i18n' of git-gui:
  git-gui: update Japanese information
  git-gui: update Japanese translation
  git-gui: add Japanese language code
  git-gui: apply po template to Japanese translation
  git-gui: consistently use the same word for "blame" in Japanese
  git-gui: consistently use the same word for "remote" in Japanese

The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.

The backquoted form is the traditional method for command
substitution, and is supported by POSIX.  However, all but the
simplest uses become complicated quickly.  In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.

The patch was generated by:

for _f in $(find . -name "*.sh")
do
	perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg'  "${_f}"
done

and then carefully proof-read.
