[xemacs-hg @ 2004-12-06 03:50:53 by ben] (none) README.packages: Document use of --package-prefix. Fix error in specifying standard package location. make-docfile.c: Use QXE_PATH_MAX. info.el: Correct doc string giving example package path. menubar-items.el: Move Prefix Rectangle command up one level. xemacs/packages.texi: Add long form of Lisp Reference Manual to links. Add links pointing to Lisp Reference Manual for more detailed package discussion. lispref/range-tables.texi: Document range-table changes. internals/internals.texi: Update history section. elhash.c, elhash.h, profile.c: Create inchash_eq() to allow direct incrementing of hash-table entry. Use in profile.c to try to reduce profiling overhead. Increase initial size of profile hash tables to reduce profiling overhead. buffer.c, device-msw.c, dialog-msw.c, dired-msw.c, editfns.c, event-msw.c, events.c, glyphs-msw.c, keymap.c, objects-msw.c, process-nt.c, syswindows.h, text.c, text.h, unexnt.c: Rename xetcs* -> qxetcs* for consistency with qxestr*. Rename ei*_c(_*) -> ei*_ascii(_*) since they work with ASCII-only strings not "C strings", whatever those are. This is the last place where "c" was incorrectly being used for "ascii". dialog-msw.c, dumper.c, event-msw.c, fileio.c, glyphs-gtk.c, glyphs-x.c, nt.c, process-nt.c, realpath.c, sysdep.c, sysfile.h, unexcw.c, unexnext.c, unexnt.c: Try to avoid differences in systems that do or do not include final null byte in PATH_MAX. Create PATH_MAX_INTERNAL and PATH_MAX_EXTERNAL and use them everywhere. Rewrite code in dumper.c to avoid use of PATH_MAX. When necessary in nt.c, use _MAX_PATH instead of MAX_PATH to be consistent with other places. text.c: Code to short-circuit when binary or Unicode was not working due to EOL wrapping. Fix this code to work when either no EOL autodetection or no CR's or LF's in the text. lisp.h, rangetab.c, rangetab.h, regex.c, search.c: Implement different types of ranges (open/closed start and end). Change default to be start-closed, end-open.
