Using an unescaped left-brace as part of an invalid repetition specification is undefined behavior.

Created attachment 182238 [details] svn(1) diff of mail/spmfilter Hello! In EREs, left-brace is not to be interpreted as an ordinary character unless escaped. Using an unescaped left-brace as part of an invalid repetition specification is undefined behavior. Attached is a patch to escape one instance of such undefined behavior usage to fix inconsistency in how we treat them between BREs and EREs. This was discovered as part of the exp-run in PR 218495. Thanks, Kyle Evans
