Use the existing C-level line number cache within #'line-number. src/ChangeLog addition: 2015-05-15 Aidan Kehoe <kehoea@parhasard.net> * buffer.c: * buffer.c (Fline_number): New C implementation, using the line number cache of line-number.c, with a new optional BUFFER argument. * buffer.c (syms_of_buffer): Make it available to Lisp. * line-number.c (buffer_line_number): New argument, RESPECT-NARROWING, describing whether to count from the beginning of the visible region or from the beginning of the buffer. * line-number.h: * line-number.h (buffer_line_number): Update its declaration. * redisplay.c (window_line_number): Call it with the new argument. lisp/ChangeLog addition: 2015-05-15 Aidan Kehoe <kehoea@parhasard.net> * simple.el: * simple.el (line-number): Moved to buffer.c; we have an existing line number cache in C, it's a shame not to have it available.

### Commentary:

## This file copies a single lisp file into an XEmacs package hierarchy and
## performs the necessary magic so that it will be autoloaded at the next
## dump.

## Parameters:
##	$1 -- Full path to an XEmacsen later than 20.3
##	$2 -- Full path to a lisp package tarball to install
##	$3 -- Full path to a lisp directory in an XEmacs package hierarchy
##	      This directory will be created if it does not exist.
##	      NOTE: the directory name should *not* end in a trailing slash


### Code:

XEMACS="$1"			# Not used at present
LISP_FILE="$2"			# Should be a binary package tarball
DEST_DIR="$3"			# Should be a top level package directory

# Test for valid XEmacs executable and valid input file
if [ ! -f "${LISP_FILE}" -o ! -x "${XEMACS}" ]; then
	exit 1
fi

# Test for destination directory, creating if necessary
test -d "${DEST_DIR}" || mkdir "${DEST_DIR}"
test -d "${DEST_DIR}" || exit 1;

# Very simple minded extraction for the first cut
# We'll get more sophisticated later
cd "${DEST_DIR}"
gunzip -c "${LISP_FILE}" | tar xvf -

# Need to refresh the info/dir file, I don't know how to do that.

exit 0
