commit-tree: encourage UTF-8 commit messages. 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".

utf8: pick_one_utf8_char() 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 pick_one_utf8_char(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

utf8_width(): allow non NUL-terminated input The original interface assumed that the input string is always terminated with a NUL, but that wasn't too useful. Signed-off-by: Junio C Hamano <gitster@pobox.com>

int is_utf8(const char *text);
commit-tree: cope with different ways "utf-8" can be spelled. People can spell config.commitencoding differently from what we internally have ("utf-8") to mean UTF-8. Try to accept them and treat them equally. Signed-off-by: Junio C Hamano <junkio@cox.net>

Add strbuf_add_wrapped_text() to utf8.[ch] The newly added function can rewrap text according to a given first-line indent, other-indent and text width. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

int strbuf_add_wrapped_text(struct strbuf *buf,
const char *text, int indent, int indent2, int width);
strbuf: add fixed-length version of add_wrapped_text The function strbuf_add_wrapped_text takes a NUL-terminated string. This makes it annoying to wrap strings we have as a pointer and a length. Refactoring strbuf_add_wrapped_text and all of its sub-functions to handle fixed-length strings turned out to be really ugly. So this implementation is lame; it just strdups the text and operates on the NUL-terminated version. This should be fine as the strings we are wrapping are generally pretty short. If it becomes a problem, we can optimize later. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
