| 294 * Since Tcl's exit is never expected to return and this replacement | |

| 297 * will be returned -- typically "attempt to call eval in deleted | |
| 298 * interpreter". Hopefully, at this point, checks for TCL_ERROR take | |
| 299 * place and control percolates back up to Vim -- but with this new error | |
| 300 * string in the interpreter's result value. Therefore it would be | |
| 301 * useless for this routine to return the exit code via Tcl_SetResult(). | |
