cmd line switch processor

[RT Happe <rthappe@mathematik.uni-freiburg.de>]

[ scsh 0.6.0 / Linux 2.2.17; scsh 0.5.2 / IRIX 6.5 ]

The command line switch processor doesn't appreciate blanks prefixing the
switches on the second line:

  #!/tmp/bin/scsh \
    -e main -s
  !#

This doesn't really hurt, but the usage instructions scsh invariably
prints when reading such a header could point to the ... feature.  (The
manual could do so, too.)  By the way, this piece of ``Usage'' and
section 11.1.4
                 meta-arg: \ <script-file-name>

is somewhat misleading.
