rfc: bye-bye "guile-tools --scriptsdir"

[Thien-Thi Nguyen]

Here is help from Guile 1.4.x guile-tools:

| Usage: guile-tools --version
|        guile-tools --help
|        guile-tools [OPTION] PROGRAM [ARGS]
| 
| If PROGRAM is "list" or omitted, display contents of scripts dir, otherwise
| PROGRAM is run w/ ARGS.  Options (only one of which may be used at a time):
|  --scriptsdir DIR    -- Look in DIR for scripts
|  --guileversion VERS -- Look in /home/ttn/local/lib/guile/VERS/scripts for 
scripts
|  --source            -- Display PROGRAM source (ignore ARGS) to stdout
|  --help-all          -- call each PROGRAM --help
| 
| Note that some PROGRAMs may also take --help or --version.
| 
| Default scripts dir: /home/ttn/local/lib/guile/1.4.1.116/scripts

I am thinking about removing support for "guile-tools --scriptsdir".
Does anyone use it?
