Hi there,
Correct if I am wrong.
If there is a .PRJ file associated with a .SHP, ogrinfo will just print
out the content of the .PRJ. Ex.:
Ivan,
It does
1) import it expecting it might be in ESRI WKT format
2) print it
"""

It will not going to run "OGRImportFromESRI()" to get EPSG Authority
codes. Isn't it right?
For Shapefile format specifically, it does run through morphing
procedure by calling OGRSpatialReference::importFromESRI
The doc may be imprecise perhaps, but IMO it suggests that:
"If a .prj files in old Arc/Info style or new ESRI OGC WKT style is
present, it will be read and used to associate a projection with features."
