Does GDB have some function can convert string to "" inside string?

Could you give me some comments about the new format for -s.

My thought is:
-s format argv1 argv2, other options

"-break-insert -s FORMAT LOCATION ARG ARG ARG ..." is too different
with current options of  -break-insert and very hard to support.
