shp2pgsql with single argument

[strk]

Allow this kind of call:

shp2pgsql lines.shp

to make up a table name looking at the shapefile name.

It already does this. Tested in 1.5 and trunk.

Great, but the help message doesn't say so:

USAGE: shp2pgsql [<options>] <shapefile> [<schema>.]<table>

Should be corrected to be:

USAGE: shp2pgsql [<options>] <shapefile> [[<schema>.]<table>]

or something like that

[jadams]

Good point. I updated the usage text.
