#543 passing parameters to .key misbehave when using spaces

[paolo besser]

The issue is well described here, with a way to reproduce it

http://aros-exec.org/modules/newbb/viewtopic.php?post_id=104048#forumpost104048

in a nutshell, when passing a parameter inclusding spaces to a script which begins with the .key command and /A/F or /F to accept every character, another space is added by mistake to the end of the entered string.

So passing a parameter like "I_have_no_mounth" is interpreted correctly, however "but I must scream" would be interpreted like "but I must scream_" (with a space instead of the last underscore).

Tested on ABIv0 i386
