 Log Message:
 PR bin/57773
 
 Fix a bug reported by Jarle Fredrik Greipsland in PR bin/57773,
 where a substring expansion where the substring to be removed from
 a variable expansion is itself a var expansion where the value
 contains one (or more) of sh's CTLxxx chars - the pattern had
 CTLESC inserted, the string to be matched against did not.  Fail.
 We fix that by always inserting CTLESC in var assign expansions.
 See the PR for all the gory details.
 
 Thanks for the PR.
 
 XXX pullup to everything.
