Fixed in r51519.

It requires some acrobatics to deal with windows' non-standard
command-line parsing, and the tcl/tk wiki devotes a long page to it
(https://blog.tcl.tk/16336). In the end, I simply replaced the full
path of perl.exe with just "perl.exe", since the batchfile wrapper
already put perl.exe on the searchpath.
