But doesn't v.in.ascii scan for column lengths in any case?
Maybe make that switchable and use the extracted info?
in point.c:
/* Analyse points ascii file. Determine number of columns and column types.
* ascii_tmp: write copy of tempfile to ascii_tmp:
* rowlength: maximum row length
* ncolumns: number of columns
* minncolumns: minimum number of columns
* column_type: column types
* column_length: column lengths (string only)
*/
int points_analyse(FILE * ascii_in, FILE * ascii, char *fs,
int *rowlength, int *ncolumns, int *minncolumns,
int **column_type, int **column_length, int skip_lines,
int xcol, int ycol, int region_flag)
