 In format_win_commandline_argument(), it would be neat to skip the
 business of building a smartlist of char*, and just pre-allocate a
 guaranteed-to-be-long-enough string -- I think that strlen(arg)*2 + 3
 would be long enough, since each character in the input turns into at most
 2 characters in the output, and there are at most 3 characters of
 overhead: 1 for the nul-terminator, 2 for quotes.

 This would actually use less RAM, since it only needs to allocate ~2 bytes
 per character, as opposed to 4 or 8 bytes per char*.  Not that it matters
 -- we don't allocate a lot of these.
