Comment (by cypherpunks):

 Replying to [comment:14 teor]:
 > I can't see the point of quoting or changing the quotes around internal
 variables or internal string literals. These are the majority of the
 changes in the patch, and I'm not sure if they gain us anything. They need
 to be weighed against the risk that a misplaced quote breaks the build on
 some obscure configuration.
 > Was there a reason for these changes?
 As stated in the ticket description, ticket:16651#comment:28 mentions a
 case where internal variables included spaces and caused issues. This was
 the reason for opening this ticket in order to prevent similar instances
 from causing problems in the future.

 tell when the last non-whitespace change was made to each line.
 I believe git has options to ignore whitespace changes so they do not
 interfere when tracking down changes. Furthermore, the tor codebase has
 numerous commits which purely fix whitespace problems to appease `make
 check-spaces`. In these cases change traceability isn't taken into account
 either so IMO we shouldn't start with it now.
