Dana Robinson b5eaacb911 [svn-r27775] Undo of r27655
Removes .pl extension from Perl scripts. This may be returned in the future,
but it's best to keep the script names unchanged while we merge with the
trunk.

# Purpose: This script will read standard input which should be a
# function prologue followed by a C function and will emit
# on standard output the same source code with the function
# prologue containing documentation for the various errors
# that occur in the function.
#
# Errors are raised by calling HGOTO_ERROR() or
# HRETURN_ERROR(). The reason for the error message is a
# comment which appears immediately after the error macro
# call and is contained entirely on one line:
#
# HRETURN_ERROR (...); /*entry not found*/
#
# If such a comment doesn't exist, then the previous comment
# is used, subject to the constraint that raising an error
# clears the previous comment.
#
# /* Entry not found */
# HGOTO_ERROR (...);
#
# Emacs users can use this script interactively with the
# c-mark-function and shell-command-on-region functions which
# are normally bound to M-C-h and M-|.
# Split STDIN into the prolog and the function body. Preserve leading
# white space.
