The column at which preformatted text should be formatted is the same as the "normal" text, so why the difference? MIN(fill_column, width) is always the correct choice for wrapping the text.

This was fixed previously in the wrap_text case but I forgot to update the hardwrap_text case too.

ncurses has "--with-termlib" build option, which forces some symbols from libncurses.so to be moved to libtinfo.so. It caused the following error: ld: ui.o: undefined reference to symbol 'keypad' ld: /lib64/libtinfow.so.6: error adding symbols: DSO missing from command line

this helps to correctly manage the tab bar when tab-bar-show is 1.

If tab-bar-show is -1 hide the tab bar permanently, if it's 0 show it unconditionally. If it's 1, show the bar only when there is more than one tab.

Don't bother computing the correct initial sizes for the windows, just call rearrange_windows before the event loop.
