Fix spaces in sed commands in sgit

New version of sgit.

Script now allows for spaces in sed commands. Thus one can do something
like:

    sgit -v3 -x -e 's/web site/website/g'  .

to set verbosity to level 3, turn on tracing (see below) and change
occurrences of 'web site' to be 'website'.

Also added -x option to turn on tracing.
