when inserting text into *Messages*.
Define it simply as a number.
(DOUBLE_FAIL_STACK, regex_compile): Set the limit at the size
TYPICAL_FAILURE_SIZE specifies, rather than at twice that much.

FAIL_STACK_GROWTH_FACTOR controls what ratio to increase size by.
proc_encode_coding_system[p->outfd] is NULL, instead of allocating
`struct coding_system' for encoding, just skip setting up coding
system for encoding. Set Vlast_coding_system_used after some text
is read.
