(ps-print-version): New version number (5.1.3).

(ps-insert-file, ps-output-boolean, ps-plot-with-face)
(ps-generate-postscript-with-faces): Code fix.
(ps-color-values): XEmacs compatibility.
(ps-print-background-image, ps-print-background-text, ps-printer-name)
(ps-default-fg, ps-default-bg): Adjust customization.
(ps-zebra-color): Adjust customization, renaming old ps-zebra-gray var.
(ps-color-scale): Renaming old ps-color-value fun.
(ps-print-headers): Replace ps-print-header group to avoid conflict
with ps-print-header variable.
(ps-print-miscellany): New group.
(ps-format-color, ps-rgb-color): New funs.
(ps-default-foreground): New var.
(ps-printer-name-option): New const.
inspection. Beginnings of support for expensive internal consistency checks.
* config.in (ENABLE_CHECKING): Undef.
* lisp.h (struct interval): Replace "parent" field with a union of interval
pointer and Lisp_Object; add new bitfield to use as discriminant. Change other
flag fields to bitfields.
(CHECK): New macro for consistency checking. If ENABLE_CHECKING is defined and
the supplied test fails, print a message and abort.
(eassert): New macro. Use CHECK to provide an assert-like facility.
* intervals.h (NULL_INTERVAL_P): Now applies only to real interval pointers;
abort if the value looks like a lisp object.
(NULL_INTERVAL_P, NULL_PARENT, HAS_PARENT, HAS_OBJECT, SET_PARENT, SET_OBJECT,
INTERVAL_PARENT, GET_INTERVAL_OBJECT, COPY_PARENT): Modify for new interval
parent definition.
* alloc.c (mark_interval_tree, MARK_INTERVAL_TREE, UNMARK_BALANCE_INTERVALS):
Update references that need an addressable lisp object in the interval
structure.
(die): New function.
(suppress_checking): New variable.
* intervals.c (interval_start_pos): Just return 0 if there's no parent object.
(appt-check): Convert min-to-app to a string before passing to
appt-disp-window-function or concat.
(appt-delete-window): Remove test for frame-root-window.
(appt-select-lowest-window, appt-convert-time): Simplify.
(iso-iso2sgml-trans-tab, iso-sgml2iso-trans-tab): New variables.
(iso-iso2sgml, iso-sgml2iso): New functions.
(iso-cvt-define-menu): Fix some entries and use backquote for
clarity.
of re_compile_fastmap and generalizing it a little bit so that it
can also just return whether a given (sub)pattern can match the empty
string or not.
(regex_compile): Use `analyse_first' to decide whether the loop-check
needs to be done or not for *, +, *? and +? (the loop check is costly
for non-greedy repetition).
(re_compile_fastmap): Delegate the actual work to `analyse_first'.
(enum re_opcode_t): Update description of succeed_n.
(PATFETCH): Always define.
(regex_compile): Use lookahead rather than PATUNFETCH (for repetition
operators, char classes, shy-groups and intervals).
Optimize special cases of intervals so as to only use succeed_n and
jump_n when really needed.
(re_compile_fastmap): Simplify handling of jump_n and succeed_n now
that we don't have to handle the special cases any more.
Simplify on_failure_jump handling as well.
