bug#52222: 27.2; invalid formatting in edebug-set-consitional-breakpoint interactive history

[Петров Андрей]

Hello!

The following test reproduces the error:

1. Instrument some function for debugging
2. Goto any line inside that function and set conditional breakpoint using 
strings in expression:
  M-x edebug-set-conditional-breakpoint RET (equal some-var "SomeString") RET
3. Set a conditional breakpoint again using interactive history:
 M-x edebug-set-conditional-breakpoint RET [up]
 I see 
    (equal some-var SomeString)
 i.e. SomeString turned into a symbol instead of string.
 This possibly may happen because of using prin1 instead of print during 
formatting history entries.
