While the current jimtcl does not consider this an error, the Tcl
dodekalogue states that strings terminate at the second double quote
character (see https://www.tcl.tk/man/tcl/TclCmd/Tcl.htm#M8).
These syntax errors were caught by tclint v0.2.5
(https://github.com/nmoroze/tclint):
```
tclint tcl/chip/st/spear/spear3xx_ddr.tcl | grep "syntax error"
```
