shp2pgsql usage touchups
|Reported by:||Mike Taves||Owned by:||pramsey|
Fixes to the usage output from shp2pgsql.
- the "-w" flag is not documented here, but is documented in using_postgis_dataman.xml (the flag is still accepted by the program, although see #603). I've reworded this, so please read-over my change.
- A few missing "."'s at the end (for consistancy)
- An unmatched ")"
- Align a few segments of text.
I have a patch for trunk, and also for 1.5.3 (if it isn't too late). However you might want to consider not adding the "-w" flag for the 1.5 branch due to #603 (unless that is an easy fix).
