Log Message:
        
        Fix some issues that mangled the reexecution path to a script,
        and thus prevented it from finding itself:
        
        * lib/general.m4sh (progname): Don't actually change the name of
        the script if it begins with a `-', just prepend `./'.
        (progpath): Add a new clause that first searches the execution
        PATH, and then finally assumes this script is in the current
        working directory if $progname has no directory separators (e.g
        when invoked as `$SHELL progname').
