* selector.c, selmatch.c: Also parse and process the experimental ":is()" and ":where()" pseudo-classes. Correct a bug in parsing comma-separated selectors. Correct a bug in esc() that caused an empty string to fail (e.g., in [alt=""]. (The function esc() is not used, but could be used when debugging.) * tests/select14.sh: Test ":empty" in combination with another pseudo-class. * Makefile.am: Added tests select26.sh, select27.sh, select28.sh, select29.sh and select30.sh * configure.ac: Added AC_SYS_LARGEFILE to enable seek() to seek large files and the off_t type to be 64 bits on older, 32-bit systems. Also check for limits.h. * hxselect.1: Noted the known bug that case-insensitive selectors (option -i) only work with ASCII characters.
