This PR was an effort to address ruby#321 (ed_quoted_insert doesn't work properly) but per the reporter it did not work correctly. Moreover, it introduced a major regression: Shell job control stopped working in all applications that use reline, notably IRB. Bash and other shells send SIGTSTP in response to C-z to implement job suspension. Handling SIGSTP opts out of this functionality. For a line oriented terminal program this should be avoided (not to mention, this behavior diverges from readline's)

Fixes #466
#335 was an effort to address #321 (ed_quoted_insert doesn't work properly) but per the reporter the change did not work correctly.
Moreover, it introduced a major regression: Shell job control stopped working in all applications that use reline, notably IRB.
Shells send SIGTSTP in response to SUSP (C-z) to implement the suspension part of job control. Adding a handler for SIGTSTP opts out of this functionality. For a line oriented terminal program this should be avoided when possible (not to mention, this behavior diverges from readline's)
