cqfd: split space removal into two variable expansions

The removal of tabulation arround the sign = is perform by two variable
expansions:
 - remove tabulation before the sign =
 - remove tabulation after the sign =

This applies the same procedure to space by splitting the single removal
into two variable expansions: one before the sign =, one after the sign
=.
