Broken: Official 2.74 release (and earlier I believe)
Short description of error
CTRL+backspace doesn't take into account underscores _ when erasing strings in text fields.
Exact steps for others to reproduce the error
Have object_name_01 in a text field and press ctrl+backspace. The whole string gets erased.
If you have object.name.01 or object:name:01 or object-name-01 ctrl+backspace erases only until it gets to the special character i.e.
The expected behavior would be to take underscore into account as well.
