• Breaking: po.compile() now wraps strings exactly like GNU gettext's msgcat. If you keep compiled .po files in version control, the next compile rewraps them once; the content does not change. (thx @cpruijsen)
• Breaking: foldLength is now the page width (like msgcat --width) and defaults to 79 instead of 76. 0 or false still disables folding.
• Fix: folding could split an escape sequence such as \t across two lines, which produced a .po file that does not parse.
