Alexander Gavrilov 69cd8f6342 builtin-blame: Reencode commit messages according to git-log rules.
Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.

This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.

Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.

If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

-b::
Show blank SHA-1 for boundary commits. This can also
be controlled via the `blame.blankboundary` config option.
--root::
Do not treat root commits as boundaries. This can also be
controlled via the `blame.showroot` config option.
--show-stats::
Include additional statistics at the end of blame output.
-L <start>,<end>::
Annotate only the given line range. <start> and <end> can take
one of these forms:
- number
+
If <start> or <end> is a number, it specifies an
absolute line number (lines count from 1).
+
- /regex/
+
This form will use the first line matching the given
POSIX regex. If <end> is a regex, it will search
starting at the line given by <start>.
+
- +offset or -offset
+
This is only valid for <end> and will specify a number
of lines before or after the line given by <start>.
+
-l::
Show long rev (Default: off).
-t::
Show raw timestamp (Default: off).
-S <revs-file>::
Use revs from revs-file instead of calling linkgit:git-rev-list[1].
-p::
--porcelain::
Show in a format designed for machine consumption.
--incremental::
Show the result incrementally in a format designed for
machine consumption.
--encoding=<encoding>::
Specifies the encoding used to output author names
and commit summaries. Setting it to `none` makes blame
output unconverted data. For more information see the
discussion about encoding in the linkgit:git-log[1]
manual page.
--contents <file>::
When <rev> is not specified, the command annotates the
changes starting backwards from the working tree copy.
This flag makes the command pretend as if the working
tree copy has the contents of the named file (specify
`-` to make the command read from the standard input).
-M|<num>|::
Detect moving lines in the file as well. When a commit
moves a block of lines in a file (e.g. the original file
has A and then B, and the commit changes it to B and
then A), traditional 'blame' algorithm typically blames
the lines that were moved up (i.e. B) to the parent and
assigns blame to the lines that were moved down (i.e. A)
to the child commit. With this option, both groups of lines
are blamed on the parent.
+
<num> is optional but it is the lower bound on the number of
alphanumeric characters that git must detect as moving
within a file for it to associate those lines with the parent
commit.
-C|<num>|::
In addition to `-M`, detect lines copied from other
files that were modified in the same commit. This is
useful when you reorganize your program and move code
around across files. When this option is given twice,
the command looks for copies from all other files in the
parent for the commit that creates the file in addition.
+
<num> is optional but it is the lower bound on the number of
alphanumeric characters that git must detect as moving
between files for it to associate those lines with the parent
commit.
-h::
--help::
Show help message.
