Description

When renaming folders, it's easy to end up with initial or trailing whitespace by mistake, which is hard to notice when viewing files. Some apps (e.g. Lightroom in Wine) fail to work with such paths. That's of course a bug in the third party app, but OTOH initial/trailing whitespace is very unlikely to be the intention of the user doing renaming. It'd be nice if Thunar's F2/Rename dialog could simply trim any initial/trailing whitespace on hitting enter.
