New version of global_gprv.gmt cannot be used by GMT

[CovMat]

Previous version of global_gprv.gmt can be easily used by GMT. For example:

#!/usr/bin/env bash

gmt begin global_gprv
    gmt basemap -JD105/35/36/42/10c -R70/140/3/60 -Baf
    gmt coast -Gwhite -S167/194/223

    # 
    gmt convert global_gprv.gmt -S"prov_type=craton" | gmt plot -G168/171/210 -t30 -l"craton"
    gmt convert global_gprv.gmt -S"prov_type=shield" | gmt plot -G217/205/228 -t30 -l"shield"
    gmt convert global_gprv.gmt -S"prov_type=passive margin" | gmt plot -G196/233/236 -t30 -l"passive margin"

    # 
    gmt convert global_gprv.gmt -S"lastorogen=Alpine-Himalayan" | gmt plot -Gred@30 -l"Alpine-Himalayan"

    # 
    gmt convert global_gprv.gmt -S"prov_name=South China Sea Basins" | gmt plot -W1.5p -l"South China Sea Basins"
    gmt convert global_gprv.gmt -S"prov_name=Ordos Block" | gmt plot -W1.5p,orange -l"Ordos Block"
gmt end show

However, new version of global_gprv.gmt can not use gmt convert -S to extract data whose header record matches a text pattern search.

Because new version of global_gprv.gmt is not OGR/GMT format:
