Feature or Bugfix
Purpose
When the user tries to align production rules, Sphinx gets confused by spaces around leading tokens. In the following, references to
mygroup:bad1
andmygroup:bad2
are missing, while the one tomygroup:correct
is present.Since it is useful to be able to align colons in a production list, this commit systematically strips leading and trailing whitespaces from the production name.
