Suppress new "may be used uninitialized" warning.
Various buildfarm members, having compilers like gcc 8.5 and 6.3, fail
to deduce that text_substring() variable "E" is initialized if
slice_size!=-1. This suppression approach quiets gcc 8.5; I did not
reproduce the warning elsewhere. Back-patch to v14, like commit
9f4fd119b2cbb9a41ec0c19a8d6ec9b59b92c125.
