Subject: [PATCH] Revert "util/dofile.pl: only quote stuff that actually needs
|
||||
quoting"
|
||||
|
||||
This wasn't a good solution, too many things depend on the quotes being
|
||||
there consistently.
|
||||
|
||||
This reverts commit 49cd47eaababc8c57871b929080fc1357e2ad7b8.
|
||||
|
||||
Fixes #5772
