Add a new helper function, strbuf_add_indented_text(), to indent text
without a width limit, and call it from strbuf_add_wrapped_text(). It
respects both indent (applied to the first line) and indent2 (applied to
the rest of the lines); indent2 was ignored by the indent-only path of
strbuf_add_wrapped_text() before the patch.
Two simple test cases are added, one exercising strbuf_add_wrapped_text()
and the other strbuf_add_indented_text().

When a zero or negative width is given to "shortlog -w<width>,<in1>,<in2>"
and --format=%[wrap(w,in1,in2)...%], just indent the text by in1 without
wrapping.

The newly added function can rewrap text according to a given first-line
indent, other-indent and text width.

print_wrapped_text() will insert its own newlines. Up until now, if the
text passed to it contained newlines, they would not be handled properly
(the wrapping got confused after that).
The strategy is to replace a single new-line with a space, but keep double
new-lines so that already-wrapped text with empty lines between paragraphs
will be handled properly.
However, single new-line characters are only handled this way if the
character after it is an alphanumeric character, as per Linus' suggestion.

utf8_width() function was doing two different things. To pick a
valid character from UTF-8 stream, and compute the display width of
that character. This splits the former to a separate function

In particular, the second parameter in the call to iconv() will
cause this warning if your library declares iconv() with the
second (input buffer pointer) parameter of type const char **.
This is the old prototype, which is none-the-less used by the
current version of newlib on Cygwin. (It appears in old versions
of glibc too).

On Cygwin the wchar_t type is an unsigned short (16-bit) int.
This results in the above warnings from the return statement in
the wcwidth() function (in particular, the expressions involving
constants with values larger than 0xffff). Simply replace the
use of wchar_t with an unsigned int, typedef-ed as ucs_char_t.

Now, it returns the current column, does not add a newline, and you can
pass a negative indent, to indicate that the indent was already printed.
With this, you can actually continue in the middle of a paragraph, not
having to print everything into a buffer first.

Introduce is_utf() to check if a text looks like it is encoded
in UTF-8, utf8_width() to count display width, and implements
print_wrapped_text() using them.
git-commit-tree warns if the commit message does not minimally
conform to the UTF-8 encoding when i18n.commitencoding is either
unset, or set to "utf-8".
